Jehovah-jireh
According to the Book of Genesis in the Bible, Jehovah-jireh (or Yahweh-yireh, YHWH will provide), was a place in the land of Moriah. It was the location of the binding of Isaac, where God told Abraham to offer his son Isaac as a burnt offering. Abraham named the place after Jehovah provided a ram to sacrifice in place of Isaac.
"And Abraham called the name of that place Jehovahjireh: as it is said to this day, In the mount of the it shall be seen." – ( KJV)
