El Olam is the Hebrew name for God who has no beginning and no end. He is the Everlasting God or the Eternal God. The first place in the Bible that we discover this name is when Abraham calls on the Everlasting God while planting a tamarisk tree in Beersheba, just after he signed a treaty with Abimelech.
It reads in Isaiah 40:28-31 NIV:
Do you not know? Have you not heard? The LORD is the everlasting God, the Creator of the ends of the earth. He will not grow tired or weary, and his understanding no one can fathom. He gives strength to the weary and increases the power of the weak. Even youths grow tired and weary, and young men stumble and fall; but those who hope in the LORD will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint.
