Les Psaumes 132:2 Midrash : Pirkei DeRabbi Eliezer & Bereshit Rabbah

What did the men of Jebus do? They made images of copper, and set them up in the street of the city, and wrote upon them the covenant of the oath of Abraham. When the Israelites came to the land (of Canaan), they wished to enter the city of the Jebusites, but they were not able (to enter), because of the sign of the covenant of Abraham's oath, as it is said, "And the children of Benjamin did not drive out the Jebusites that inhabited Jerusalem" (Judg. 1:21). || When David reigned he desired to enter the city of the Jebusites, (but) they did not allow him, as it is said, "And the king and his men went to Jerusalem against the Jebusites, the inhabitants of the land; which spake unto David, saying, Thou shalt not come in hither" (2 Sam. 5:6).

“Jacob took a vow, saying: If God will be with me, and He will keep me on this way that I go, and will give me bread to eat, and a garment to wear” (Genesis 28:20).
“Jacob took a vow, saying: If God will be with me…and will give me bread to eat.” It is written: “Those uttered by my lips and spoken by my mouth when I was in distress” (Psalms 66:14) – Rabbi Yitzḥak HaBavli said: “And spoken by my mouth when I was in distress” – as he vowed to perform a mitzva in his time of distress. What is “saying”? It is: Saying to the generations, so they would take vows in their time of distress. Jacob began with a vow first; therefore, anyone who takes a vow will ascribe the vow only to him. Rabbi Abbahu said: It is written: “Who took an oath to the Lord and took a vow to the Champion of Jacob” (Psalms 132:2) – to the Champion of Abraham or to the Champion of Isaac is not written here, but rather, “took a vow to the Champion of Jacob” – he ascribed the vow to the one who began with it first.
