SEV Biblia, Chapter 21:4
Y circuncidó Abraham a su hijo Isaac de ocho días, como Dios le mandó.
Clarke's Bible Commentary - Genesis 21:4
Verse 4. And Abraham circumcised his son] See note on ""chap. xvii. 10"", &c.
Matthew Henry Commentary
Verses 1-8 - Few under the Old Testament were brought into the world with suc expectations as Isaac. He was in this a type of Christ, that Seed whic the holy God so long promised, and holy men so long expected. He wa 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 goo reason for the name, ch. 17:17; 18:13. When the Sun of comfort is rise upon the soul, it is good to remember how welcome the dawning of the day was. When Sarah received the promise, she laughed with distrust an doubt. When God gives us the mercies we began to despair of, we ough to remember with sorrow and shame our sinful distrust of his power an promise, when we were in pursuit of them. This mercy filled Sarah with joy and wonder. God's favours to his covenant people are such a surpass their own and others' thoughts and expectations: who coul imagine that he should do so much for those that deserve so little nay, for those that deserve so ill? Who would have said that God shoul send his Son to die for us, his Spirit to make us holy, his angels to attend us? Who would have said that such great sins should be pardoned such mean services accepted, and such worthless worms taken int covenant? A short account of Isaac's infancy is given. God's blessin upon the nursing of children, and the preservation of them through the perils of the infant age, are to be acknowledged as signal instances of the care and tenderness of the Divine providence. See Ps 22:9, 10; He 11:1, 2.
