A Birth, A Rivalry, And A Covenant (21:1-34)
Neal Pollard
We have constant reminders in the Bible that God keeps His promises, even ones that seem impossible or far-fetched. The chapter begins with the assertion that the Lord “took note” of Sarah, doing what He promised (1; 17:15-21; 18:10-14). The name “Isaac” (laughter) is fitting since both Abraham and Sarah laughed when they were first given the promise from God, but at his birth a different kind of laughter filled their home (6-7). There is abundant joy as this elderly couple welcome the son of promise into their family. Domestic tranquility does not last forever, though. The rivalry that first appeared between Sarah and Hagar has transferred to the next generation.
Ishmael mocks Isaac on the day he is weaned (9). Sarah makes the extraordinary demand that Abraham drive out Hagar and Ishmael, for whom he felt responsibility–especially for his first-born son. Yet, God assures Abraham that what Sarah wants is appropriate (12; Gal. 4:30) and that He will take care of them in the wilderness. He assures Abraham that Ishmael would father a nation, since he was his descendant (13). But “through Isaac [his] descendants would be named” (12).
Undoubtedly, Hagar is not privy to this revelation Abraham received. She is left to cope with the frightening prospect of fending for herself and her teenage son with only the bread and water Abraham sends her away with (14). She wanders about and when the supplies run out, she braces for their deaths (15-16). They are helpless on their own, but God intervenes.
I find several interesting parallels between what happens in this chapter with Hagar and Ishmael and what happens in the next chapter with Abraham and Isaac. First, both leave Beersheba at the command of God. Second, each time a son of Abraham faced seeming certain death. Third, neither time do we hear the child speak in protest or self-defense. Fourth, the angel of the Lord speaks in both cases to intervene. Fifth, God makes promises about the descendants of both sons. Finally, God opens the eyes of both parents to see what God provided, for Sarah a well of water and for Abraham a ram.
God is with Hagar. He develops a life-preserving skill (archery) and his mother finds him a wife from their native Egypt. They live in the wilderness of Paran, a place we first encounter in the wars of Genesis 14:6. It is between Canaan and Egypt, northeast of Mt. Sinai. It will be the site of much of the wilderness wanderings in Numbers as well as the place David goes following Samuel’s death (1 Sam. 25:1ff).
With the domestic issues settled and Abraham and Sarah fully focused on raising Isaac, a familiar face reemerges in their lives–Abimelech (22-33). He and his army commander can see how God is blessing everything Abraham had and did, and so they want there to be a covenant between the two clans. They swear peace between themselves, but Abraham has a complaint against Abimelech’s servants (25). They had seized the well of water Abraham’s servants were using. Abimelech, seemingly consistent with his character as revealed in Genesis, is totally unaware of such a breach and did not endorse it. Abraham shows great wisdom in gifting sheep and oxen and making a covenant with him (27). Additionally, he provides Abimelech seven ewe lambs, explaining to the puzzled king that they were a witness that he had dug the well at the place he calls Beersheba (“the well of the oath” or “swearing by seven lambs”).
After Abimelech and Phicol return to the coastal area called here “the land of the Philistines” (32), Abraham plants a tamarisk tree there and worships “the Lord, the Everlasting God” (33). He resides for many days at what apparently was the northern end of Abimelech’s domain (Smith, 160). Abraham continues to do what he has been doing, publicly worshipping his God (12:8; 13:4).
The table certainly seems set. They have the improbable son of promise. There is no domestic strife or competition between sons to distract the family. They are at peace with their neighbors. Life is good! How often do we encounter the calm before the storms of life, blissfully ignorant of impending crisis? Faith and spiritual strength are built in such times of peace and help us weather the storms that inevitably calm. We will see this more clearly when we turn the page to chapter 22.
