Charles H. Spurgeon on Psalms 122:4

The testimony of Israel. The object which is represented in the Psalm as having power to attract all hearts, and command the ready attendance of the tribes, is "the testimony of Israel, "the revelation, in other words, which God made to that people of his character, feelings, and purposes, as most holy, yet ready to forgive, a just God and the Saviour. This discovery of the nature of that great Being before whom all must appear, is justly regarded as a ground of joy. Robert Nisbet.

Verses 4-5. Observe what a goodly sight it was to see the testimony of Israel and the thrones of judgment such near neighbours; and they are good neighbours, which may greatly befriend one another. Let "the testimony of Israel" direct the "thrones of judgment, "and the "thrones of judgment" protect "the testimony of lsrael." Matthew Henry.
