Jeremiah 35:16 New English Translation

¹⁶Yes,^[a] the descendants of Jonadab son of Rechab have carried out the orders that their ancestor gave them. But you people^[b] have not obeyed me!

Jeremiah 35:16 tn This is an attempt to represent the particle כִּי (ki), which is probably not really intensive here (cf. BDB 472 s.v. כִּי 1.e) but is one of those causal uses of כִּי that BDB discusses on 473-74 s.v. כִּי 3.c, where the cause is really the failure of the people of Judah and Jerusalem to listen/obey. That is, the causal particle is at the beginning of the sentence so as not to interrupt the contrast drawn.
Jeremiah 35:16 tn Heb “this people.” However, the speech is addressed to the people of Judah and the citizens of Jerusalem, so the second person is retained in English. In addition to the stylistic difference that Hebrew exhibits in the rapid shifts between persons (second to third and third to second, which have repeatedly been noted and documented from GKC 462 §144.p), there may be a subtle rhetorical reason for the shift here. The shift from direct address to indirect address that characterizes this verse and the next may reflect the Lord’s rejection of the people he is addressing. A similar shift takes place in Wisdom’s address to the simpleminded, fools, and mockers in Prov 1:28-32 after the direct address of 1:22-27.
