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:”

KJV

Meaning

The divine oath marks the seriousness of the moment and connects Abraham's tested faithfulness with a reaffirmation of covenant blessing.

This unique narrative must not be converted into a principle that God rewards parents for endangering or surrendering their children to harm.

The promise is reaffirmed after Isaac is spared, so the story's future depends on preservation rather than on completing the threatened sacrifice.
