As in many stories about the patriarchs (early fathers of Israel), the key meaning is preserved through naming. Yahweh-Yireh means "the Lord will provide" (see 22:8). The use of the divine name Yahweh (the personal name of God) shows that the patriarchs knew this name (compare Exodus 6:2–3), even if they did not yet understand its full meaning (see study note on Exodus 6:2–3).
to this day: Later Israelites saw this story as a lesson about their worship in Jerusalem. Abraham's sacrifice happened on the mountain of the Lord, which later became the site of the temple in Jerusalem (see study note on 22:2). Three times a year, the people of Israel brought their best offerings to God for sacrifice. They trusted he would continue to provide for them.
