Jeremiah 4:3-5

Amplified Bible

“Plow your uncultivated ground [for a season],
And do not sow among thorns.
⁴ 
“Circumcise (dedicate, sanctify) yourselves to the Lord
And remove the foreskin [sins] of your heart,
Men of Judah and inhabitants of Jerusalem,
Or else My wrath will go forth like fire [consuming all that gets in its way]
And burn and there will be no one to quench it,
Because of the evil of your acts.”

⁵ 
Declare in Judah and proclaim in Jerusalem, and say,
“Blow the trumpet in the land;
Cry aloud and say,
‘Assemble yourselves, and let us go
Into the fortified cities.’
