'Obtain' in the Bible

Sarai said to Abram, "See now, Yahweh has restrained me from bearing. Please go in to my handmaid. It may be that I will obtain children by her." Abram listened to the voice of Sarai.

She said, "Behold, my maid Bilhah. Go in to her, that she may bear on my knees, and I also may obtain children by her."
