15:21. And the Amorrhites, and the Chanaanites, and the Gergesites, and
the Jebusites.

Genesis Chapter 16

Abram marrieth Agar, who bringeth forth Ismael.

16:1. Now Sarai, the wife of Abram, had brought forth no children: but
having a handmaid, an Egyptian, named Agar,

16:2. She said to her husband: Behold, the Lord hath restrained me from
bearing: go in unto my handmaid, it may be I may have children of her at
least. And when he agreed to her request,

16:3. She took Agar the Egyptian her handmaid, ten years after they
first dwelt in the land of Chanaan, and gave her to her husband to wife.

To wife... Plurality of wives, though contrary to the primitive
institution of marriage, Gen. 2.24, was by divine dispensation allowed
to the patriarchs: which allowance seems to have continued during the
time of the law of Moses. But Christ our Lord reduced marriage to its
primitive institution. Matt. 19.

16:4. And he went in to her. But she perceiving that she was with child,
despised her mistress.

16:5. And Sarai said to Abram: Thou dost unjustly with me: I gave my
handmaid into thy bosom, and she perceiving herself to be with child,
despiseth me. The Lord judge between me and thee.
