Jeremiah 1:12 New English Translation

¹²Then the Lord said, “You have observed correctly. This means^[a] I am watching to make sure my threats are carried out.”^[b]

Jeremiah 1:12 tn This represents the Hebrew particle (כִּי, ki) that is normally rendered “for” or “because.” The particle here is meant to give the significance of the vision, not the rationale for the statement “you have observed correctly.”
Jeremiah 1:12 tn Heb “watching over my word to do it.”sn There is a play on the Hebrew word for “almond tree” (שָׁקֵד, shaqed) and the word “watching” (שֹׁקֵד, shoqed). The vision is not the prophecy but is simply the occasion for the prophecy. Getting Jeremiah to say shaqed (almond tree) becomes the occasion for God to announce he is shoqed (watching). The verb refers to someone watching over someone or something in preparation for action. Compare Jer 1:13-14 and Amos 7:7-8; 8:1-2, which each follow the formula of God asking the prophet what he sees and then giving a prophecy based on a sound play. Here the play on words announces the certainty and imminence of the Lord carrying out the covenant curses of Lev 26 and Deut 28 threatened by the earlier prophets.
