Charles Ellicott Commentary Psalms 74:8

"They said in their heart, Let us make havoc of them altogether: They have burned up all the synagogues of God in the land." — Psalms 74:8 (ASV)

All the synagogues of God in the land. —This expression excludes from moed either of the meanings possible for it in Psalms 74:4: “the Temple” or “the assembly.” Buildings, and these places of worship, must be meant. It is implied that they are scattered over the land and, therefore, can mean nothing but synagogues.

The “high places” would not be called God’s, nor would Bethel and Dan have been so called, being connected with irregular and unorthodox worship. Thus, we have a clear note of time, indicating a period not only later than the rise of the synagogue in Ezra’s time but much later, since it takes time for a new institution to spread over a country.

Aquila and Symmachus actually render “synagogues.” Possibly, the Septuagint is right in putting the latter clause into the mouth of the enemies: “let us burn,” etc.
