Midrash for Judges 1:8

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).
