Ulangan 27:26

27:26 ‘Cursed is the one who refuses to keep the words of this law.’ Then all the people will say, ‘Amen!’

Yeremia 11:3

11:3 Tell them that the Lord, the God of Israel, says, ‘Anyone who does not keep the terms of the covenant will be under a curse. ¹ 

[11:3]  ¹ tn Heb “Cursed is the person who does not listen to the terms of this covenant.” “This covenant” is further qualified in the following verse by a relative clause. The form of the sentence and the qualification “my” before covenant were chosen for better English idiom and to break up a long sentence which really extends to the middle of v. 5.
