“shofar.” The ram’s horn trumpet, not the metal trumpet.

“lost.” The Hebrew word is 'abad (#06 אָבַד) and it has a wide enough meaning to include both those who are already dead and those who were perishing. Thus it implies both a resurrection of the dead and a gathering of the living (cp. Matt. 25:31-46, the Sheep and Goat Judgment; see commentary on Matt. 25:32).

“worship.” The Hebrew word translated “worship,” shachah (#07812 שָׁחָה), is the same Hebrew word as “bow down.” This verse could be translated the way it currently is, or “They will bow down to Yahweh.”

[For more on bowing down, see commentary on 1 Chron. 29:20.]
