John Gill Commentary Psalms 94:5

"They break in pieces thy people, O Jehovah, And afflict thy heritage." — Psalms 94:5 (ASV)

They break in pieces your people, O Lord
Not the Israelites, as Kimchi; but the church of Christ, by their anathemas, cruel edicts, and persecutions; by confiscating their goods, imprisoning their persons, putting them to cruel deaths; and by such means think to "wear out" the saints of the most High, the Lord's covenant and peculiar people; which is mentioned as an aggravation of their sin, and as an argument with the Lord to arise on their behalf:

and afflict your heritage ;
the church, styled God's heritage, (1 Peter 5:3) , whom the Lord has chosen for his inheritance; and are dear to him, as his portion, his jewels, and even as the apple of his eye; and yet these are afflicted all manner of ways by their persecuting enemies, as Israel was of old in Egypt.
