1 Samuel 1:20-21

Wherefore it came to pass, when the time was come about after Hannah had conceived, that she bare a son, and called his name Samuel, {saying}, Because I have asked him of the LORD. {when...: Heb. in revolution of days} {Samuel: that is, Asked of God} And the man Elkanah, and all his house, went up to offer unto the LORD the yearly sacrifice, and his vow.
