They take the timbrel and harp, and rejoice at the sound of the organ.
Take - rather, lift up the voice (sing) to the note of х naasaa' (H5375)] (Isaiah 42:11). (Umbreit.)
Timbrel - rather, tambourine.
Organ - not the modern "organ," but the 'pipe' (Genesis 4:21). The first clause refers to stringed, the latter to wind instruments; thus, with 'the voice,' all kinds of music are enumerated.
