Man is bowed down, and men are brought low repeats 2.9 (see the comments there). As in 2.9, Man and men are general terms for (all) people and should be so translated.

And the eyes of the haughty are humbled is synonymous with the first line. It is almost identical to the first line of 2.11 (see the comments there). Eyes refers to how people look around and thus their attitude.

In this verse there is a difference in tense between Revised Standard Version and Good News Translation: Revised Standard Version uses present tense while Good News Translation has future, probably with “that day” in mind (see 2.11).

Alternative translation models for this verse are:

• Everyone will be brought low and humbled,
people’s arrogant looks will be removed.

• Every person will be brought low, all will be humbled,
their arrogant looks will be removed.
