Genesis 21:2

Genesis 21:2, &c. Sarah—bare Abraham a son, &c.— Isaac at last is born; the wonder and expectation of his day. Observe,

1. The fulfilment of the promise, when all human prospects were at an end; when Abraham was as dead, and Sarah past the time of child-bearing. Note; (1.) Promised mercies will come in God's time. (2.) God can work for us, when we most despair of ourselves. (3.) What nature cannot do, faith can, Hebrews 11:11.

2. Abraham's carefulness to observe God's prescribed order, to circumcise him on the eighth day, and give him the name of Isaac. Note; When our hearts are circumcised, and our new name given us, as sons of Abraham, Isaac's, sons of laughter, then shalt we rejoice with joy unspeakable and full of glory.
