Psalms 91:4

Verse 4. Strings, upon. Hebrew “on the hasor, and on the nabel, on the higaion with the cinnor.” Yet the ten stringed instrument seems to have been the same with the psaltery, or nobol. Bible.—Bellarmin thinks and is redundant, and was not in the copies of the Septuagint or it is only explanatory, as we know that the psaltery had ten strings. Psalms 32:2 and 143:9. Menochius.—The matter is of small consequence. Bert.—Eusebius seems to insinuate, that instruments were not used in the Church of his time. Calmet.—The observance of the commandments, and mortification, signified by the harp are requisite. Worthington.
