Haggai said that Yahweh was with them (Hag 1:13-1:13)

“Then Haggai,

The messenger of Yahweh,

Spoke to the people

With Yahweh’s message,

Saying.

‘I am with you,

Says Yahweh.’”

The prophet Haggai, who was a messenger from Yahweh, spoke to the assembled people of Jerusalem to reassure them that Yahweh was with them.  This reassurance or presence of Yahweh was his main message.

Yahweh is with you (Zeph 3:16-3:17)

“On that day,

It shall be said

To Jerusalem.

‘Do not fear!

O Zion!

Do not let your hands

Grow weak!

Yahweh!

Your God!

Is in your midst!

He is a warrior

Who gives victory.

He will rejoice

Over you

With gladness.

He will renew you

In his love.

He will exult

Over you

With loud singing

As on a day of festival.”

Zephaniah emphasized that on that great day, Jerusalem would have Yahweh in their midst.  They were not to fear or let their hands grow weak.  Yahweh, their God, would be a warrior for them.  Yahweh was going to rejoice and be glad about them.  He would renew them with his love.  He would exult over them with loud singing, as on the various festival days.
