And he brought forth his people with joy,.... Or "therefore" , in consequence of his promise, and the remembrance of it, he brought Israel out of Egypt with great joy to them, they coming out with so much health and wealth; having their liberty, and in hope of shortly being settled in a land flowing with milk and honey.
Andhis chosen with gladness: or "singing" ; especially when they had got through the Red sea, their enemies drowned, and they quite clear of them, Ex 15:1. And when they are called "his chosen", this opens another source of those blessings to them, not only the promise and covenant of God, but their election of God, which was free and sovereign, to choose them above all people; not because they were better or more than others, but because he loved them; and hence he did all the above things for them.
In like manner when God's elect are in the effectual calling, brought out of bondage to liberty, out of darkness to light, out of an horrible pit, and have their feet set on a rock; are brought to Christ and into his church, and have a place and a name there; it is with exceeding great joy and gladness to them; and to the church above shall they at last be brought with everlasting joy on their heads, Isa 35:10.
