The verse literally is—
Then said Haggai, the messenger of Jehovah in the message of
Jehovah to the people, saying,
I am with you, saith Jehovah.
The word for “messages” is in the plural number, preceded by the preposition [ב]. Why commentators have generally rendered it in the singular number, does not appear. Haggai is expressly said to be God’s messenger in, or with regard to, the messages or communications he made to the people. To connect the word, as
some do, with “said,” hardly gives a meaning, except the clause be rendered, as it is done by Newcome, “by the message of Jehovah,” that is, by his command; but then a plural word is made singular.—Ed.
