John Gill's Exposition of the Bible
Hebrews 11:18

Of whom it is said
That is, of Isaac, Abraham's own son, whom he offered up; or rather, "to whom it was said", as the Vulgate Latin and Syriac versions render it; that is, to Abraham, for to him was this said, ( Genesis 21:12 )

that in Isaac shall thy seed be called;
that numerous natural seed of his, which should inherit the land of Canaan; and his special famous seed, the Messiah, to whom the promises were made; (See Gill on Romans 9:7).
