211 And Jehovah visited Sarah as he had said, and Jehovah did to Sarah as he had spoken. 2 And Sarah conceived, and bore Abraham a son in his old age, at the appointed time of which God had spoken to him. 3 And Abraham called the name of his son who was born to him, whom Sarah bore to him, Isaac. 4 And Abraham circumcised his son Isaac, being eight days old, as God had commanded him. 5 And Abraham was a hundred years old when his son Isaac was born to him. 6 And Sarah said, God has made me laugh: all that hear will laugh with me. 7 And she said, Who would have said to Abraham, Sarah will suckle children? For I have borne [him] a son in his old age.
8 And the child grew, and was weaned. And Abraham made a great feast on the day that Isaac was weaned.
9 And Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, mocking. 10 And she said to Abraham, Cast out this handmaid and her son; for the son of this handmaid shall not inherit with my son—with Isaac. 11 And the thing was very grievous in Abraham's sight because of his son. 12 And God said to Abraham, Let it not be grievous in thy sight because of the lad and because of thy handmaid: [in] all that Sarah hath said to thee hearken to her voice, for in Isaac shall a seed be called to thee. 13 But also the son of the handmaid will I make a nation, because he is thy seed.
14 And Abraham rose up early in the morning, and took bread, and a flask of water, and gave [it] to Hagar, putting [it] on her shoulder—and the child, and sent her away. And she departed, and wandered about in the wilderness of Beer-sheba. 15 And the water was exhausted from the flask; and she cast the child under one of the shrubs, 16 and she went and sat down over against [him], a bow-shot off; for she said, Let me not behold the death of the child. And she sat over against [him], and lifted up her voice and wept. 17 And God heard the voice of the lad. And the Angel of God called to Hagar from the heavens, and said to her, What [aileth] thee, Hagar? Fear not; for God hath heard the voice of the lad there, where he is. 18 Arise, take the lad, and hold him in thy hand; for I will make of him a great nation. 19 And God opened her eyes, and she saw a well of water; and she went and filled the flask with water, and gave the lad drink. 20 And God was with the lad, and he grew; and he dwelt in the wilderness, and became an archer. 21 And he dwelt in the wilderness of Paran. And his mother took him a wife out of the land of Egypt.

(Read Genesis 21:1-8)
Few under the Old Testament were brought into the world with such expectations as Isaac. He was in this a type of Christ, that Seed which the holy God so long promised, and holy men so long expected. He was born according to the promise, at the set time of which God had spoken. God's promised mercies will certainly come at the time which He sets, and that is the best time. Isaac means "laughter," and there was good reason for the name, Psalm 22:9,10; Hosea 11:1,2.
Commentary on Genesis 21:9-13
(Read Genesis 21:9-13)
Let us not overlook the manner in which this family matter instructs us not to rest in outward privileges, or in our own doings. And let us seek the blessings of the new covenant by faith in its Divine Surety. Ishmael's conduct was persecution, being done in profane contempt of the covenant and promise, and with malice against Isaac. God takes notice of what children say and do in their play; and will reckon with them, if they say or do amiss, though their parents do not. Mocking is a great sin, and very provoking to God. And the children of promise must expect to be mocked. Abraham was grieved that Ishmael should misbehave, and Sarah demand so severe a punishment. But God showed him that Isaac must be the father of the promised Seed; therefore, send Ishmael away, lest he corrupt the manners, or try to take the rights of Isaac. The covenant seed of Abraham must be a people by themselves, not mingled with those who were out of covenant: Sarah little thought of this; but God turned aright what she said.
Commentary on Genesis 21:14-21
(Read Genesis 21:14-21)
If Hagar and Ishmael had behaved well in Abraham's family, they might have continued there; but they were justly punished. By abusing privileges, we forfeit them. Those who know not when they are well off, will be made to know the worth of mercies by the want of them. They were brought to distress in the wilderness. It is not said that the provisions were spent, or that Abraham sent them away without money. But the water was spent; and having lost their way, in that hot climate Ishmael was soon overcome with fatigue and thirst. God's readiness to help us when we are in trouble, must not slacken, but quicken our endeavours to help ourselves. The promise concerning her son is repeated, as a reason why Hagar should bestir herself to help him. It should engage our care and pains about children and young people, to consider that we know not what great use God has designed them for, and may make of them. The angel directs her to a present supply. Many who have reason to be comforted, go mourning from day to day, because they do not see the reason they have for comfort. There is a well of water near them in the covenant of grace, but they are not aware of it, till the same God that opened their eyes to see their wound, opens them to see their remedy. Paran was a wild place, fit for a wild man; such as Ishmael. Those who are born after the flesh, take up with the wilderness of this world, while the children of the promise aim at the heavenly Canaan, and cannot be at rest till they are there. Yet God was with the lad; his outward welfare was owing to this.
