“Do not lay a hand on the boy or do anything to him,” said the angel, “for now I know that you fear God, since you have not withheld your only son from me.”
Jewish Publication Society of America Version (JPS1917) - Genesis 22:12 >And he said: 'Lay not thy hand upon the lad, neither do thou any thing unto him; for now I know that thou art a God-fearing man, seeing thou hast not withheld thy son, thine only son, from Me.'
