And after that shall they come forth. — The verse combines the promise to Abraham in Genesis 15:17 with a free rendering of the sign given to Moses (Exodus 3:12), which referred not to Canaan but to Horeb. What St. Stephen does is to substitute with the natural freedom of a narrative given from memory the words “they shall serve me” for the simpler phrase, “they shall come hither again,” of Genesis. The whole context is at variance with the assumption that St. Stephen meant the last words of the verse to be taken as applying to the mount of God.
