Charles Ellicott Commentary Jeremiah 31:4

"Again will I build thee, and thou shalt be built, O virgin of Israel: again shalt thou be adorned with thy tabrets, and shalt go forth in the dances of them that make merry." — Jeremiah 31:4 (ASV)

You shall again be adorned with your tabrets ... —The implied idea is that of a time of rejoicing after triumphant restoration (the “building” of the previous sentence is more than that of material walls and towers), when the daughters of Israel (Judges 11:34; 1 Samuel 18:6; Psalms 68:11) should again go forth with “timbrels and dances,” with tabrets and joy and instruments of music. The “tabret” was a musical instrument of the drum type, somewhat like the Spanish or Italian tambourine, with bells attached to the metal hoop.
