First reading: Genesis 15:5-12,17-18

Taking Abram outside, the Lord said, ‘Look up to heaven and count the stars if you can.’ ‘Such will be your descendants,’ he told him. Abram put his faith in the Lord, who counted this as making him justified.

‘I am the Lord’ he said to him ‘who brought you out of Ur of the Chaldaeans to make you heir to this land.’ ‘My Lord,’ Abram replied ‘how am I to know that I shall inherit it?’ He said to him, ‘Get me a three-year-old heifer, a three-year-old goat, a three-year-old ram, a turtledove and a young pigeon.’ He brought him all these, cut them in half and put half on one side and half facing it on the other; but the birds he did not cut in half. Birds of prey came down on the carcases but Abram drove them off.

Now as the sun was setting Abram fell into a deep sleep, and terror seized him. When the sun had set and darkness had fallen, there appeared a smoking furnace and a firebrand that went between the halves. That day the Lord made a Covenant with Abram in these terms:

‘To your descendants I give this land,
from the wadi of Egypt to the Great River.’
