Leviticus 23:23-25

Lev 23:23 And Yahveh spoke to Moses, and this is what he said,
Lev 23:24 “Speak to the people of Israel, and this is what you should say, In the seventh month, on the first day of the month, you will observe a day of solemn rest, a memorial proclaimed with blast of trumpets, a holy convention.
Lev 23:25 You will not do any ordinary work, and you will present a fire offering to Yahveh.”

with blast of trumpets

The feast of trumpets introduces a whole month of special celebrations in the covenant community. Are the trumpets intended to instill fear or to provoke excitement and joy. The answer is yes. It all depends on your relationship with God. Just like resurrection day, when the last trumpet will sound. That same trumpet call will rescue the dead in Christ from their mortality and set them free to live forever, so it will be a joyful sound. But that same trumpet will call the angels of heaven to bring death and disaster on the planet as a judgment against all powers that have stolen dominion from the Lord, so it will be a fearsome sound.

LORD, we are straining to hear your trumpet blast. Come and rescue us, and restore your creation.
