Genesis 21:1

And the LORD visited Sarah as he had said, and the LORD did unto Sarah as he had spoken.

The long-looked for blessing of a son to Abraham and Sarah, is at length bestowed; and Isaac, the child of promise, is born. This Chapter relates the auspicious event. The casting out of Ishmael, the Son of Hagar, the bond-woman, is also noticed, with the circumstances attending it. Some inferior matters, which occurred in Abraham's family, and a covenant of amity, which the Patriarch entered into with Abimelech; form the remainder of the particulars, related in this Chapter.

That is a precious Scripture of the prophet, Habakkuk 2:3. And the apostle's comment upon it, is not less so. Hebrews 10:36, etc. These words are not only applicable in the case of the Patriarch's trials of faith, but have been refreshing to thousands in their various exercises.
