Whither {d} the tribes go up, the tribes of the LORD, unto the testimony of Israel, to give thanks unto the name of the LORD.

(d) All the tribes according to God's covenant will come and pray there.

Wesley's Notes

122:4 The tribes - Whom God has chosen to be his people. Unto - Unto the ark, called the testimony, because of the tables of the covenant laid up in it, which are called God's testimony, and the tables of the testimony. And this is called the testimony of, or to Israel, because it was given by God to them. Give thanks - To worship God; this one eminent part thereof being put for all the rest.

Jamieson-Fausset-Brown Bible Commentary

4. testimony-If "unto" is supplied, this may denote the ark (Ex 25:10-21); otherwise the act of going is denoted, called a testimony in allusion to the requisition (De 16:16), with which it was a compliance.

Matthew Henry's Concise Commentary

122:1-5 The pleasure and profit from means of grace, should make us disregard trouble and fatigue in going to them; and we should quicken one another to what is good. We should desire our Christian friends, when they have any good work in hand, to call for us, and take us with them. With what readiness should we think of the heavenly Jerusalem! How cheerfully should we bear the cross and welcome death, in hopes of a crown of glory! Jerusalem is called the beautiful city. It was a type of the gospel church, which is compact together in holy love and Christian communion, so that it is all as one city. If all the disciples of Christ were of one mind, and kept the unity of the Spirit in the bond of peace, their enemies would be deprived of their chief advantages against them. But Satan's maxim always has been, to divide that he may conquer; and few Christians are sufficiently aware of his designs.
