'Shoulders' in the Bible

And said unto the Levites that taught all Israel, which were holy unto the LORD, Put the holy ark in the house which Solomon the son of David king of Israel did build; it shall not be a burden upon your shoulders: serve now the LORD your God, and his people Israel,

"Put the holy ark in the Temple that Solomon, the son of Israel's King David, built. It will no longer be a burden on their shoulders. Now go serve the LORD your God and his people Israel. Prepare yourselves by divisions according to your ancestral households, keeping to what King David of Israel and his son Solomon wrote about this.
