'I Am with You' in the Bible

Then spoke Haggai, Jehovah's messenger, in Jehovah's message unto the people, saying, I am with you, saith Jehovah.

But now be strong, Zerubbabel, saith Jehovah; and be strong, 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.
