Joel 2:15

Blow the trumpet in Zion
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 hearts and not your garments, and return to the LORD your God. For He is gracious and compassionate, slow to anger, abounding in loving devotion. And He relents from sending disaster.

14 Who knows? He may turn and relent and leave a blessing behind Him— grain and drink offerings for the LORD your God.

15 Blow the ram’s horn in Zion, consecrate a fast, proclaim a sacred assembly.

16 Gather the people, sanctify the congregation, assemble the aged, gather the children, even those nursing at the breast. Let the bridegroom leave his room, and the bride her chamber.

17 Let the priests who minister before the LORD weep between the portico and the altar, saying, “Spare Your people, O LORD, and do not make Your heritage a reproach, an object of scorn among the nations. Why should they say among the peoples, ‘Where is their God?’”
