Psalms 122:4 - Clarke's commentary and critical notes on the Bible

Whither the tribes go up, the tribes of the LORD, unto the testimony of Israel, to give thanks unto the name of the LORD. The testimony of Israel - There is the ark, where the presence of God is manifested; there is the holy of holies; and there all the tribes assembled to worship Jehovah. He no doubt alludes to the assembling of the tribes annually at each of the three grand national festivals.
