Midrash su Salmi 91:1

Why was he called Bezalel? Because he constructed a place of shade for God,⁶See above, n. 3. as it is said: Thou shalt dwell in the covert of the Most High, and abidest in the shadow of the Almighty (Ps. 91:1).

(Numb. 7:1:) “So it came to pass on the day that Moses had finished.” R. Johanan said, “What is the meaning of ‘on the day that [Moses] had finished (rt.: klh)?’ [Finished is] a word for annihilation (rt.: klh).⁹³Numb. R. 12:3, end; cf. 23:9; similarly PRK 1:5; PR 5:10. On the day that the Tabernacle was erected the destructive demons (mazziqin) were annihilated (rt.: klh) from the world.” Before that Tabernacle was erected, the destructive demons had been common in the world. When Moses went up on the mountain, he said this psalm (i.e., Ps. 91, which begins), “Whoever dwells in the shelter of the Most High,” in that he (Moses) did dwell in the shelter of the Holy One, blessed be He.⁹⁴Numb. R. 12:3, beginning. (Ibid., cont.:) “He lodges in the shadow (tsel) of the Almighty,” in that he lodged there a hundred and twenty days, like the numerical count of [the letters in the word,] tsel. (Vs. 2) “[I will] say to the Lord, my refuge [and my fortress (metsudah)],” in that He is my refuge and has become⁹⁵‘ShWY. Buber omits the final letter of this word in his text, but has restored it where he cites the passage in n. 142. like a wall for me. (Ibid., cont.:) “My God, in whom I trust.” The Holy One, blessed be He, said to him, “You have put your trust in Me; by your life, I am standing up for you.” (Vs. 3:) “That he will deliver you from the snare of the fowler.” What is the meaning of “from the snare of the fowler?” From the trap⁹⁶Metsodah. The same written word voweled as metsudah means “fortress” and appears as such in the previous verse of the psalm. of David, who [would have been] seized to be killed, as stated (in II Sam. 23:26) “and Saul and his men were trying to encircle David and his men and capture them.” (Vs. 4:) “You will take refuge under His wings; His truth is a shield and buckler.” Resh Laqish said, “I have become a shield for whoever takes refuge in the Torah.” (Vs. 5:) “You shall not be afraid of any terror by night.” From here [we learn] that they were afraid of destructive demons. (Ibid., cont.:) “Nor of the arrow that flies by day.” R. Berekhyah the Priest Berabbi said, “There is a destructive demon (mazziq) that flies like a bird and shoots forth like an arrow.”⁹⁷Deut. R. 6:6. (Vs. 6:) “Of the pestilence that walks in the darkness, of the plague that lays waste at noonday.” This is the plague demon, Meriri; for whoever sees him will not survive in the world, whether he be human, cattle, or wild beast. How is he made? His head resembles a calf with one horn coming out of the middle of his forehead, and he is made of obsidian. And Meriri has dominion from the seventeenth of Tammuz (around July) to the ninth of Av (around August).⁹⁸Lam. R. 1:3 (29). The first breach in the walls of Jerusalem was made on Tammuz 17, and the Temple was destroyed on Av 9, exactly three weeks later. This period was also the hottest time of the year. [It is] therefore [written] (in vs. 6), “of the plague that lays waste at noonday.” (Vs. 10:) “There shall no evil come unto you, neither shall pestilence come near your tent.” This is the tent of meeting. Ergo, until the day that the Tabernacle was erected, the destructive demons (mazziqin) were common,⁹⁹See PRK 1:5. and on the day that the Tabernacle was erected they were annihilated (rt.: klh). R. Simeon b. Laqish said, “What [reason] is there for me to learn [this] from the book of Psalms? It is [to be] learned from its [proper] place (in Numb. 6:24), “The Lord bless you and keep you” [from the destructive demons] and from all evil. When? On the day that the Tabernacle was erected.

Another interpretation (of Numb. 7:1): SO IT CAME TO PASS ON THE DAY THAT MOSES HAD FINISHED. R. Johanan said: What is the meaning of ON THE DAY THAT <MOSES> HAD FINISHED (rt.: KLH)? <FINISHED is> a word for annihilation (rt.: KLH).¹¹⁶Tanh., Numb. 2:23; Numb. R. 12:3, end; cf. 23:9; similarly PRK 1:5; PR 5:10. On the day that the Tabernacle was erected the destructive demons (mazziqin) were annihilated (rt.: KLH) from the world. Before that Tabernacle was erected, the destructive demons had been common in the world. When Moses went up on the mountain, he said this Psalm (i.e., Ps. 91, which begins): WHOEVER DWELLS IN THE SHELTER OF THE MOST HIGH, in that he (Moses) did dwell in the shelter of the Holy One.¹¹⁷Numb. R. 12:3, beginning. (Ibid., cont.:) HE LODGES IN THE SHADOW OF THE ALMIGHTY, in that he lodged there a hundred and twenty days. (Vs. 2) <I WILL> SAY TO THE LORD, MY REFUGE < AND MY FORTRESS (metsudah) >, in that he is my refuge and has become¹¹⁸‘ShWY. Buber omits the final letter of this word in his text, but has restored it where he cites the passage in n. 142. like a wall for me. (Ibid., cont.:) MY GOD, IN WHOM I TRUST. The Holy One said to him: You have put your trust in me; [by your life,] I am standing up for you. (Vs. 3:) THAT HE WILL DELIVER YOU FROM THE SNARE OF THE FOWLER. [What is the meaning of FROM THE SNARE OF THE FOWLER?] From the trap¹¹⁹Metsodah. The same written word voweled as metsudah means “fortress” and appears as such in the previous verse of the psalm. of a hunter. (Vs. 4:) YOU WILL TAKE REFUGE UNDER HIS WINGS; HIS TRUTH IS A SHIELD AND BUCKLER. Resh Laqish said: I have become a shield for whoever deals¹²⁰Soher. The Buber text may be misreading this word. It should perhaps agree with the parallel in Tanh., Numb. 2:23, which reads hoseh. This reading matches the wording of the Psalm and results in the rendering, “for whoever takes refuge (hoseh) in the Torah.” The parallel in Numb. R. 12:3, however, agress with the Buber text. in the Torah. (Vs. 5:) YOU SHALL NOT BE AFRAID OF ANY TERROR BY NIGHT. [From here] <we learn> that they were afraid. (Ibid., cont.:) NOR OF THE ARROW THAT FLIES BY DAY. Rabbi Berekhyah the Priest [Berabbi] said: There is a destructive demon (mazziq) that flies like a bird and shoots forth like an arrow.¹²¹Deut. R. 6:6. (vs. 6:) OF THE PESTILENCE THAT WALKS IN THE DARKNESS, OF THE PLAGUE THAT LAYS WASTE AT NOONDAY. This is the plague demon, Meriri; for whoever sees him will not survive [in the world], whether he be human, cattle, or wild beast. How does it happen? His head resembles a calf with one horn coming out of the middle of his forehead, and he has dominion from the seventeenth of Tammuz (around July) to the ninth of Av (around August).¹²²Lam. R. 1:3 (29). The first breach in the walls of Jerusalem was made on Tammuz 17, and the Temple was destroyed on Av 9, exactly three weeks later. This period was also the hottest time of the year. It is therefore written (in vs. 6 & 10): OF THE PLAGUE THAT LAYS WASTE AT NOONDAY…. THERE SHALL NO EVIL COME UNTO YOU, NEITHER SHALL PESTILENCE COME NEAR YOUR TENT. Ergo: until the day that the Tabernacle was erected, the destructive demons (mazziqin) were common.¹²³See PRK 1:5. On the day that the Tabernacle was erected they were annihilated (rt.: KLH). {R. Simeon b. Gamaliel} [R. Simeon b. Laqish] said: What <reason> is there for me to learn <this> from the book of Psalms? It is <to be> learned from its <proper> place (in Numb. 6:24): THE LORD BLESS YOU <to keep you> from the destructive demons AND KEEP YOU from all evil. When? On the day that the Tabernacle was erected. (Numb. 7:1): SO IT CAME TO PASS ON THE DAY THAT MOSES HAD FINISHED.
