Charles Spurgeon Commentary Haggai 2:4

"Yet now be strong, O Zerubbabel, saith Jehovah; and be strong, O Joshua, son of Jehozadak, the high priest; and be strong, all ye people of the land, saith Jehovah, and work: for I am with you, saith Jehovah of hosts," — Haggai 2:4 (ASV)

This is the second time that Haggai was sent with this message.

It was so rich, so full, so divinely encouraging, that the Lord might well repeat it: I am with you, saith the Lord of hosts.
