Jeremiah 11:18

New English Translation

¹⁸The Lord gave me knowledge, that I might have understanding.^[a]
Then he showed me what the people were doing.^[b]

Jeremiah 11:18 tn Heb “caused me to know that I might know.” Many English versions supply an unstated object, “their plots,” that is referred to later in the context (cf. v. 19). The presupposition of this kind of absolute ellipsis is difficult to justify and would also create the need for understanding an ellipsis of “it” after “I knew.” It is better to see a bipolar use of the verb “know” here. For the second use of the verb “know” meaning “have understanding,” see BDB 394 s.v.יָדָע Qal.5.
Jeremiah 11:18 tn Heb “Then you showed me their deeds.” This is another example of the rapid shift in person that is common in Jeremiah. As elsewhere, it has been resolved, for the sake of avoiding confusion for the English reader, by leveling the referent to the same person throughout. The text again involves an apostrophe, a shift from talking about the Lord to addressing him.
