85 Heb “When they are hot.”
86 The translation follows the suggestion of 707 עָלַז and a number of modern commentaries (e.g., Bright, J. A. Thompson, and W. L. Holladay) in reading יְעֻלְּפוּ (ye’ulléfu) for יַעֲלֹזוּ (ya’alozu) in the sense of “swoon away” or “grow faint” (see 710 עָלַף Pual). That appears to be the verb that the (the Greek version) was reading when they translated καρωθῶσιν (karōthōsin, “they will be stupefied”). For parallel usage cites Isa 51:20. This fits the context much better than “they will exult” in the Hebrew text.
87 The central figure here is the figure of the cup of the Lord’s wrath (cf. 25:15–29, especially v. 26). Here the Babylonians have been made to drink so deeply of it that they fall into a drunken sleep from which they will never wake up (i.e., they die, death being compared to sleep [cf. Ps 13:3 (13:4 ); 76:5 (76:6 ); 90:5]). Compare the usage in Jer 51:57 for this same figure.
88 Heb “Oracle of the Lord.”

In other versions

While they are inflamed I will prepare them a feast

and make them drunk, that they may become merry,

then sleep a perpetual sleep

and not wake, declares the Lord.

But while they are aroused,

I will set out a feast for them

and make them drunk,

so that they shout with laughter—

then sleep forever and not awake,”

declares the Lord.

While they are flushed with heat, I will serve them a feast,

and I will make them drunk so that they celebrate.

Then they will fall asleep forever

and never wake up.

This is the Lord’s declaration.

And while they lie inflamed with all their wine,

I will prepare a different kind of feast for them.

I will make them drink until they fall asleep,

and they will never wake up again,”

says the Lord.

At their becoming hot I will set their banquets,

and I will make them drunk,

so that they will fall into a swoon,

and they will sleep an everlasting sleep,

and they will not wake up,” declares Yahweh.

In their heat I will make their feasts,

And I will make them drunken, that they may rejoice,

And sleep a perpetual sleep,

And not wake, saith the Lord.
