7 Then he said to him, “I am the Lord who brought you from Ur of the Chaldeans, to give you this land to possess.” 8 But he said, “O Lord God, how am I to know that I shall possess it?” 9 He said to him, “Bring me a heifer three years old, a female goat three years old, a ram three years old, a turtledove, and a young pigeon.” 10 He brought him all these and cut them in two, laying each half over against the other; but he did not cut the birds in two. 11 And when birds of prey came down on the carcasses, Abram drove them away.
12 As the sun was going down, a deep sleep fell upon Abram, and a deep and terrifying darkness descended upon him. 13 Then the Lord[c] said to Abram, “Know this for certain, that your offspring shall be aliens in a land that is not theirs, and shall be slaves there, and they shall be oppressed for four hundred years; 14 but I will bring judgment on the nation that they serve, and afterward they shall come out with great possessions. 15 As for yourself, you shall go to your ancestors in peace; you shall be buried in a good old age. 16 And they shall come back here in the fourth generation; for the iniquity of the Amorites is not yet complete.”
17 When the sun had gone down and it was dark, a smoking fire pot and a flaming torch passed between these pieces. 18 On that day the Lord made a covenant with Abram, saying, “To your descendants I give this land, from the river of Egypt to the great river, the river Euphrates, 19 the land of the Kenites, the Kenizzites, the Kadmonites, 20 the Hittites, the Perizzites, the Rephaim, 21 the Amorites, the Canaanites, the Girgashites, and the Jebusites.”
Jeremiah 34: 17-20
Therefore, thus says the Lord: You have not obeyed me by granting a release to your neighbors and friends; I am going to grant a release to you, says the Lord—a release to the sword, to pestilence, and to famine. I will make you a horror to all the kingdoms of the earth. 18 And those who transgressed my covenant and did not keep the terms of the covenant that they made before me, I will make like[c] the calf when they cut it in two and passed between its parts: 19 the officials of Judah, the officials of Jerusalem, the eunuchs, the priests, and all the people of the land who passed between the parts of the calf 20 shall be handed over to their enemies and to those who seek their lives. Their corpses shall become food for the birds of the air and the wild animals of the earth.
I don’t understand what this covenant is all about. Could you explain it?
