Ulangan 13:2

13:2 and the sign or wonder should come to pass concerning what he said to you, namely, “Let us follow other gods” – gods whom you have not previously known – “and let us serve them.”

Yeremia 44:29

44:29 Moreover the Lord says, ¹  ‘I will make something happen to prove that I will punish you in this place. I will do it so that you will know that my threats to bring disaster on you will prove true. ² 

[44:29]  ¹ tn Heb “oracle of the Lord.”

[44:29]  ² tn Heb “This will be to you the sign, oracle of the Lord, that I will punish you in this place in order that you may know that my threats against you for evil/disaster/harm will certainly stand [see the translator’s note on the preceding verse for the meaning of this word here].” The word “sign” refers to an event that is a pre-omen or portent of something that will happen later (see BDB 16 s.v. אוֹת 2 and compare usage in 1 Sam 14:10; 2 Kgs 19:29). The best way to carry that idea across in this context seems to be “I will make something happen to prove [or portend].” Another possibility would be “I will give you a pre-omen that,” but many readers would probably not be familiar with “omen/pre-omen.” Again the sentence has been broken in two and restructured to better conform with English style.
