Genesis 22:16

And said, By myself have I sworn, saith the LORD, for because thou hast done this thing, and hast not withheld thy son, thine only [son]:

Ver. 16. By myself have I sworn.] God swears for the further confirmation of our faith. For here he swore, not more for Abraham's sake, than ours, as the apostle shows. Hebrews 6:13,14 ; Heb 6:17-18 As when he spake with Jacob at Penuel, "there he spake with us "; Hos 12:4 and what he said to Joshua, he said to all, "I will not leave thee, nor forsake thee". Heb 13:5

And hast not withheld thy son, thine only son.] And yet what was this to that sic without a sicut that hyperbole, that excess of love in God, that moved him to send his Son to die for our sins? He loved Christ far better than Abraham could love Isaac; and yet he gave him up freely, which Abraham would never have done without a command and to die as a malefactor, and by the hands of barbarous and bloody enemies; whereas Isaac was to die as a holy sacrifice, and by the hand of a tender father. How much more cause have we to say, Now I know the Lord loves me: and to swear as David did, to "keep his righteous judgments". Psa 119:106
