“And the man Elkanah, and all his house, went up to offer unto the LORD the yearly sacrifice, and his vow.”
King James Version (KJV)
1:21 His house - Hannah only and her child excepted. His vow - By which it appears, though it was not expressed before, that he heard and consented to her vow, and that he added a vow of his own, if God answered his prayers.
