'Obtain' in the Bible

And there was strife and quarreling between the herdsmen of Abram’s cattle and the herdsmen of Lot’s cattle. Now the Canaanite and the Perizzite were living in the land at that same time [making grazing of the livestock difficult].

And Sarai said unto Abram, Behold now, the LORD hath restrained me from bearing: I pray thee, go in unto my maid; it may be that I may obtain children by her. And Abram hearkened to the voice of Sarai.

And she said, Behold, my maid Bilhah, go in unto her; that she may bear upon my knees, and I also may obtain children by her.
