Midrash su Salmi 110:3

Another interpretation (of Gen. 12:1): GO (LK LK). The Holy One said to him: I sought (rt.: ShHR) you (LK) early. Thus R. Joshua ben Qorhah said: David said (in Ps. 110:3): YOUR PEOPLE ('MK) OFFER THEMSELVES WILLINGLY IN THE DAY OF YOUR WARFARE (rt.: HYL)… < FROM THE WOMB OF THE DAWN (rt.: SHHR). > YOURS (LK) IS THE DEW OF YOUR YOUTH.¹³Cf. Gen. R. 39:8. The Holy One said to him: I was with you ('MK) on the day that you armed your forces (rt.: HYL). What is the meaning of THE DEW OF YOUR YOUTH? R. Aha said: R. Hanina said: At the age of three years Abraham recognized his Creator.¹⁴See Gen. R. 30:8; 46:2; 64:8; 95:3; Cant. R. 5:16:1; PR 21:12; below, 5:6. Where is it shown? Where it is stated (in Gen. 26:5): BECAUSE ('QB) ABRAHAM HEEDED MY VOICE. By gematria¹⁵Gk.: geometria or grammateis. Gematria is an exegetical method in which an interpretation is reached from the sum of the numerical value of the letters in a word. 'QB = 172 < years >, and all the days of Abraham are 175 < years >. Hence¹⁶By understanding Gen. 26:5 to mean: 172 YEARS ABRAHAM HEEDED MY VOICE. you learn that at the age of three years Abraham knew his Creator. The Holy One said to him: I am making all the evil deeds which you did in those three years like this dew. Ergo (in Ps. 110:3): THE DEW OF YOUR YOUTH.

David also gives praise⁴⁷Gk.: kalos (“beautifully,” “well”). (in Ps. 110:3): YOUR PEOPLE OFFER THEMSELVES FREELY IN YOUR DAY OF VALOR. Now where is it shown that the righteous were collaborators with the Holy One when he formed a model? Where it is so written (in I Chron. 4:23): THESE WERE THE FORMERS, [EVEN] THE INHABITANTS OF NETAIM…. < These are > [the ones who are] collaborators with God in all creation, as stated (ibid., cont.): THEY DWELL THERE ALONG WITH THE KING AT HIS WORK; i.e., they dwell along with the Supreme King of Kings, the Holy One, at his work, and create creation. The Holy One said: It is not enough that I do nothing without their knowledge, but everything which I make in this world and in the world to come is prepared for them. That is what David said (in Ps. 31:20 [19]): HOW ABUNDANT IS THE GOOD WHICH YOU HAVE LAID UP FOR THOSE WHO FEAR YOU….
