ISB ~ 1 Corinthians 15 v52

the last trumpet:The final blast that will inaugurate the general resurrection (1 Thess 4:16). • Several uses of the trumpet in ancient Israel fill out the background to this image. The trumpet was a liturgical instrument that summoned Israel to meet the Lord (Ex 19:16-17), to worship him on the Feast of Trumpets (Lev 23:23-25), and to enjoy his rest every jubilee year (Lev 25:9). The trumpet was also a military instrument that called soldiers into battle (Judg 7:19-23; Jer 4:19). These uses overlapped in the conquest of Jericho, where the military operation against the city was itself a liturgical action of processing and blowing trumpets (Josh 6:1-21). Trumpet imagery is also used in the Prophets to signal Israel’s restoration from the covenant death of exile (Is 27:13) and to commence the judgment of the wicked on the “day of the Lord” (Joel 2:1; Zeph 1:15-16).
