19 And God said, Sarah thy wife shall indeed bear thee a son; and thou shalt call his name Isaac; and I will establish my covenant with him, for an everlasting covenant for his seed after him.
We praise Thee, Lord of glory,
Established Heir of all;
Creation's wondrous story
Thy greatness doth recall.
God's glory in effulgence
In Thee the Son is seen;
Expression of His substance,
We hail Thee now supreme!
