In Chapter VIII we learn that the king of Nimrod heard from the wise men that
they had seen a sign in the heavens that Abram would "who will grow up and be fruitful, and multiply, and possess all the earth, he and his children for ever, and he and his seed will slay great kings, and inherit their lands."
As a consequence of this he wanted to kill Abram but Terah (Abram's father) sent the king the son of a servant (who the king then murdered).
Terah then hid Abram, his mother and nurse in a cave for 10 years.

VIII
32
And it was in the third day that the king sent to Terah, saying, Send me thy son for a price as I spoke to thee; and shouldst thou not do this, I will send and slay all
thou hast in thy house, so that thou shalt not even have a dog remaining.
33
And Terah hastened, (as the thing was urgent from the king),
and he took a child from one of his servants, which his handmaid had born to him that day,
and Terah brought the child to the king and received value for him.
34
And the Lord was with Terah in this matter, that Nimrod might not
cause Abram's death, and the king took the child from Terah and with all his might dashed
his head to the ground, for he thought it had been Abram; and this was concealed from him
from that day, and it was forgotten by the king, as it was the will of Providence not to
suffer Abram's death.
35
And Terah took Abram his son secretly, together with his mother and nurse,
and he concealed them in a cave, and he brought them their provisions monthly.
36
And the Lord was with Abram in the cave and he grew up, and Abram was in the
cave ten years, and the king and his princes, soothsayers and sages, thought that the
king had killed Abram.
