Jeremiah 23:5-6

We cannot earn it, we cannot buy it…grace is the gift of God to all those who believe in the salvation only He could provide in Jesus Christ. Why? So that no man can boast.

There is no man righteous…no, not one!

The Messiah fulfills the expectation for the Davidic king. Faithlife Bible.

The days of the Messiah’s reign would bring salvation. Both Judah and Israel would be restored. The name that characterizes this ideal king is THE LORD OUR RIGHTEOUSNESS. Contrast that to the name Zedekiah, which means “The Lord Is My Righteousness”. Zedekiah’s name was a gross misnomer compared to the One who would establish the true, righteous rule—God’s appointed king. This verse is one of the texts in the Hebrew Bible that speaks specifically and surely of the coming of the glorious Savior and King. NKJ Bible.

Righteousness—marks His Godhead, for God alone can justify the ungodly. Jamieson, R., Fausset, A. R., & Brown, D. (1997). 

Jeremiah 23:5–6 (NKJV)

⁵ “Behold, the days are coming,” says the Lord,

“That I will raise to David a Branch of righteousness;

A King shall reign and prosper,

And execute judgment and righteousness in the earth.

⁶ In His days Judah will be saved,

And Israel will dwell safely;

Now this is His name by which He will be called:

THE LORD OUR RIGHTEOUSNESS

Psalm 72:2 (NKJV)

² He will judge Your people with righteousness,

And Your poor with justice.

Isaiah 9:7 (NKJV)

⁷ Of the increase of His government and peace

There will be no end,

Upon the throne of David and over His kingdom,

To order it and establish it with judgment and justice

From that time forward, even forever.

The zeal of the Lord of hosts will perform this.
