Taber

ta'-ber (taphaph, "to strike a timbrel" ((Ps 68:25)): The word is used only once in the King James Version, namely, in the exceedingly graphic account of the capture of Nineveh given in Na 2:7. The queen (perhaps the city personified) is dishonored and led into ignominious captivity, followed by a mourning retinue of "maids of honor" who taber upon, that is, beat violently, their breasts. Such drumming on the breasts was a gesture indicative of great grief (Lu 18:3).
