'Reward' in the Bible

Behold, the Lord God will come with might,With His arm ruling for Him.Behold, His reward is with HimAnd His recompense before Him.

“I have aroused him in righteousnessAnd I will make all his ways smooth;He will build My city and will let My exiles go free,Without any payment or reward,” says the Lord of hosts.

But I said, “I have toiled in vain,I have spent My strength for nothing and vanity;Yet surely the justice due to Me is with the Lord,And My reward with My God.”

Behold, the Lord has proclaimed to the end of the earth,Say to the daughter of Zion, “Lo, your salvation comes;Behold His reward is with Him, and His recompense before Him.”
