Melachim Alef 18:31 Meaning and Commentary

1 Kings 18:31

And Elijah took twelve stones, according to the number of the
tribes of the sons of Jacob
Which he might very easily come at from the mountain:

unto whom the word of the Lord came, saying, Israel shall be thy name,
which signifies one that has power with God, as Jacob had, when the word came to him to make a change in his name at Penuel, ( Genesis 32:28 ) , and as Elijah hoped and believed he should have at this time, being a prophet, and a worshipper of Israel's God.
