King James Version (KJV)
Then I said, I have laboured in vain, I have spent my strength for nought, and in vain: {yet} surely my judgment {is} with the LORD, and my work with my God. {my work: or, my reward}
Modern English
But I said, “I have labored in vain. I have spent my strength in vain for nothing; yet surely the justice due to me is with Yahweh, and my reward with my God.”
Hebrew
