Praise the LORD with harp: sing unto him with the psaltery and an instrument of ten strings.
Praise ... harp. The voice is felt inadequate to do justice to the glory of God: the aid of instruments is enlisted.
The psaltery (and) an instrument of ten strings - rather, as the old version all translate, one instrument only is meant, 'with the lyre of ten strings' х neebel (H5035) `aasowr (H6218)] Josephus says the strings were twelve. But some lyres may have had but ten. The Hebrew for lyre originally meant a leather bottle. From its shape, the lyre was so called [Greek, nabla]. It was played with the fingers, not with the quill (cf. Psalms 92:3; Psalms 144:9).
