Commentaries:
From a spiritual perspective, what did God tell the apostle John (in the type; Revelation 11:1) that he was to do first? He was to measure the Temple, and the altar, and the worshippers. What is the first thing that Elijah does in this circumstance? He repairs the altar. He gets things prepared for a proper witness for God by repairing the altar—preparing it to offer sacrifices.
