“Your only son, whom you love”
Take your son… your only son Isaac, whom you love, and go to the land of Moriah. Offer him there as a burnt offering on one of the mountains, which I will show you. (Genesis 22:2 BSB)
What it sounds like today
A cruel and inexplicable command to kill a child.
The cultural key
The horror of the command is sharpened, not softened, by its cultural setting: child sacrifice was practiced by Israel's Canaanite and Phoenician neighbors, so the demand sounds, at first, like what the surrounding gods required. The story lets that dread build to the last second and then reverses it: God stops the knife and provides a ram in Isaac's place, an emphatic repudiation of the very practice the test seemed to invoke. 'Only son' (yachid) does not deny Ishmael's existence but names Isaac as the one son of the promise; the location, Moriah, is later identified with the temple mount.
Recovered meaning
The most agonizing test in Scripture trades on a real and terrible custom, then dismantles it: the God who asks does not want the child dead but provides the substitute himself. Jewish tradition calls it the Akedah, the binding, and Christians read the beloved, only son carrying the wood up Moriah as a shadow of another hill.
