Jeremiah 48:30 New English Translation

³⁰I, the Lord, affirm that^[a] I know how arrogant they are.
But their pride is ill founded.
Their boastings will prove to be false.^[b]

Jeremiah 48:30 tn Heb “Oracle of the Lord.”
Jeremiah 48:30 tn The meaning of this verse is somewhat uncertain: Heb “I know, oracle of the Lord,/ his arrogance and [that it is?] not true; // his boastings accomplish that which is not true.” Several modern English versions and commentaries redivide the verse and read something like, “I know his insolence…his boastings are false; his deeds are false” (NRSV, REB). However, the word translated “deeds” in the last line is a verb in the third person plural and can only have as its logical grammatical subject the word “boastings.” The adjective כֵּן (ken) + the negative לֹא (lo’) are evidently repeated here and applied to two different subjects, “arrogance” and “boasting,” to emphasize that Moab’s arrogant boasts will prove “untrue” (cf. HALOT 459 s.v. II כֵּן 2.c for the meaning “untrue” for both this passage and the parallel one in Isa 16:6). There is some difference of opinion about the identification of the “I” in this verse. Most commentators see it as referring to the prophet. However, F. B. Huey (Jeremiah, Lamentations [NAC], 395) is probably correct in seeing it refer to the Lord. He points to the fact that the “I” in vv. 33, 35, 38 can only refer to God. The “I know” in v. 30 also clearly has the Lord as its subject. There are other cases in the book of Jeremiah where the Lord expresses his lament over the fate of a people (cf. 14:1-6, 17-18).
