Joel 2:15

For the calling of the people together to religious duties, which was one use of the silver trumpets made for and blows by the priests, ( Numbers 10:2 Numbers 10:3 Numbers 10:8 Numbers 10:10 ) ; sanctify a fast, call a solemn assembly; (See Gill on Joel 1:14).

Joel 2:15 In-Context

13 So rend your heart, and not your garments; Return to the Lord your God, For He is gracious and merciful, Slow to anger, and of great kindness; And He relents from doing harm.

14 Who knows if He will turn and relent, And leave a blessing behind Him-- A grain offering and a drink offering For the Lord your God?

15 Blow the trumpet in Zion, Consecrate a fast, Call a sacred assembly;

16 Gather the people, Sanctify the congregation, Assemble the elders, Gather the children and nursing babes; Let the bridegroom go out from his chamber, And the bride from her dressing room.

17 Let the priests, who minister to the Lord, Weep between the porch and the altar; Let them say, "Spare Your people, O Lord, And do not give Your heritage to reproach, That the nations should rule over them. Why should they say among the peoples, 'Where is their God?' "
