Midras Ayub 12:13: Midrash Tanchuma Buber, Mekhilta DeRabbi Yishmael, Midrash Tanchuma & Bereshit Rabbah

(Exod. 13:17:) NOW IT CAME TO PASS, WHEN PHARAOH HAD LET <THE PEOPLE> GO…. This text is related (to Job 9:4): ONE WISE OF HEART AND MIGHTY IN STRENGTH—WHO HAS HARDENED HIMSELF AGAINST HIM AND PROSPERED? [ONE WISE OF HEART:] This is the Holy One, as stated (in Job 12:13): WITH HIM ARE WISDOM AND {UNDERSTANDING} [VALOR]. (Job 9:4, cont.:) WHO HAS HARDENED HIMSELF AGAINST HIM AND PROSPERED? The generation of the flood hardened themselves against him; so he washed them away with water. The generation of the dispersion hardened themselves against him; <so> he dispersed them throughout the world. The people of Sodom hardened themselves against him, and what was their end? (Gen. 19:24:) THEN THE LORD RAINED DOWN UPON SODOM <… BRIMSTONE AND FIRE.> (Exod. 5:2:) PHARAOH SAID: WHO IS THE LORD? For the Holy One had said to him (in vs. 1): LET MY PEOPLE GO; but he also hardened himself, as stated (in Exod. 13:15): AND IT CAME TO PASS, WHEN PHARAOH HARDENED HIMSELF AGAINST LETTING {THEM} [US] GO. As soon as the plague of the first-born came upon him, he immediately let them go. It is therefore stated (in Exod. 13:17): NOW IT CAME TO PASS, WHEN PHARAOH HAD LET < THE PEOPLE > GO….

"I shall sing to the L–rd," who is wise — (Mishlei 2:6) "For the L–rd shall give wisdom. From His mouth are knowledge and understanding", (Daniel 2:21) "He gives wisdom to the wise, and knowledge to the knowers of understanding". (Jeremiah 10:7) "Who will not fear You, King of the nations? For among all the sages of the nations and in all of their kingdoms, there is none like You."

As to His wisdom: The Lord by wisdom founded the earth (Prov. 3:19); With Him is wisdom and might (Job 12:13); With Him is strength and sound wisdom (ibid., v. 16); For the Lord giveth wisdom; out of His mouth cometh knowledge and discernment (ibid. 2:6). It likewise says: He giveth wisdom unto the wise, and knowledge to them that know understanding (Dan. 2:21), and Forasmuch as among all the wise men of the nations, and in all their royalty, there is none like unto Thee (Jer. 10:7).
