Comentario citado sobre Josué 10:13

ויכלו השמים והארץ וכל צבאם, this verse refers to both the hosts of heaven and the hosts of earth, including their respective derivatives, תולדותם. They had all been completed on the sixth “day,” and henceforth there would not be any new phenomena in the universe, unless created by a special act of miracle. The fact is, that already during the first six “days” when the laws of nature were formulated by the Creator, He inserted escape clauses into this system of natural law that would allow Him, if and when required, to temporarily suspend such laws at His discretion.
This is explained in Bereshit Rabbah 5,5 where Rabbi Yochanan (or Yonathan) is quoted as saying that G’d entered into an agreement with the oceans that when the time would come they would respond to Moses’ command to be split, etc., in order for the Israelites at that time to cross on dry land. This is the meaning of the words in Exodus 14,26 וישב הים לפנות בוקר לאיתנו, “the sea returned towards morning to its original format.” This is a reference to the condition which G’d had imposed on the sea at the time He set certain rules for it to follow. Rabbi Yirmiyah ben Eliezer added that G’d had not only made such arrangements with the oceans, but also with all other phenomena which He had created during those six “days;” this is reflected by Isaiah 45,12אני, ידי נטו שמים וכל צבאם צויתי, “My own hands stretched out the heavens and I marshaled their host.” The extra word צויתי, refers to this clause. We also have Joshua 10,13 in which Joshua is described as arresting the sun and the moon in their respective orbits. Had it not been for the provision by G’d at the time of the creation of these planets, Joshua could not have successfully ordered them to perform what would have been an act of disobedience against the rules set for them by G’d. The same holds true for G’d’s dispatching the ravens to feed meat to the prophet Elijah (Kings I 17,4-6), or His ordering the fire not to burn Chananyah, Mishael and Azaryah. (Daniel 3,23) G’d had also ordered the lions not to harm Daniel (Daniel 6,26). Similarly, G’d had commanded the whale to swallow Jonah, keep him alive, etc. (Jonah 2,11)

This Book commonly known as The Book of Bereishis, is referred to by the Prophets as Sefer HaYashar, the Book of the Upright, as stated in Tractate Avodah Zarah 25a pertaining to the two [following] verses:
1. “And the sun stood still, and the moon stayed, until the people had avenged themselves upon their enemies. Is this not written in the Sefer HaYashar?”¹Josh. 10:13.This verse refers to the miracle, where Yehoshua ordered the sun and the moon to stand still so that the Israelites could destroy their enemies in battle before nightfall. See Avodah Zarah ad loc.: “Where [in Genesis is the miracle of the staying of the sun and moon] alluded to? [In the verse where Yaakov blesses Ephraim, Yehoshua’s ancestor:] The awe of his offspring will fill the nations (Gen. 48:19)
2. “And he said to teach the Sons of Yehuda the bow. Behold it is written in the Sefer HaYashar.”²II Sam. 1:18. In his eulogy for King Saul and his fallen sons, David states that it is written in the Sefer HaYashar that the children of Yehuda are the ones most suited for archery. Tractate Avodah Zarah ad loc continues: Where [in Genesis is Yehuda mastery of archery] alluded to? [In the verse where Yaakov blesses Judah:] Judah – you, your brothers shall acknowledge, your hand will be at the nape of your enemies (Gen. 49:8). Which form of warfare requires the hand to be raised opposite the nape? You must say that it is the method used with the archer’s bow.”
R’ Yochanan [ad loc.] explains that [Sefer HaYashar] is the book, [Bereishis, depicting the lives] of Avraham, Yitzchak and Yaakov, who were called “upright” [by Bilaam ]³This was recited by Bilaam the Wicked, who was hired by Balak, King of Moab to curse the Nation of Israel. The meaning of this phrase will be explained below., as stated, “Let me die the death of the upright.” ⁴Num. 23:10. ….

Be still. Selah: – His meaning is: “Be silent, and cease to rebel against me;” for “stillness” has the sense of silence of speech and voice, as “They kept still for my counsel” (Job 29:21); “stillness and a voice I heard” (ibid. 4:16). There is also (a stillness) which is (equivalent to) silence of action and movement, as “He turneth the storm to stillness” (Ps. 107:29); “my bowels boil and are not still” (Job 30:27); “and the sun stood still” (Josh. 10:13); “Be still (tarry) until we come unto you” (1 Sam. 14:9); “To the still stone” (Hab. 2:19), and (other instances) similar to these. And of this meaning is (the sentence) Be still: Selah, as though to say: “Cease you from your works.” And the great teacher of righteousness, our master Moses ben Maimon, has explained (Guide for the Perplexed, Bk. 1:50, 59) that this verse commands men of intelligence and reputation to recognise the truth and the praise of God in their hearts, so that no error of speech shall overtake them. But this is not (derived) from the sense of the Psalm.
