They break in pieces thy people, O Jehovah! Having spoken of their discourse or language as vain-glorious and shameless, he proceeds to speak of their deeds, in cruelly persecuting the Church. It is hard that even the subjects of heathen princes should be subjected to unjust persecution, but a more intolerable thing still, that those who are God's own people, his peculiar inheritance, should be trampled under the foot of tyranny. The prayer before us is one which, as I have already remarked, is given with the intention that we should prefer it ourselves, when we or others may be persecuted by wicked men, and especially intestine enemies. Our safety is dear to the Lord, not only as we are men, the workmanship of his hand, but as we are his peculiar heritage; and this should lead us, when wronged at any time, to betake ourselves to God with the more confidence. It is farther added -- that they spare not the widow, and the orphan, and murder the stranger God, while he has commanded us in general to cultivate equity and justice in our common intercourse, has commended the orphan, widow, and stranger, to our peculiar care, as being more exposed to injury, and therefore more entitled to humanity and compassion. To treat such objects with cruelty argues a singular degree of impiety, and contempt of divine authority, and is not only an outrage of common justice, but the infraction of a privilege of special protection which God has condescended to cast around them. They who are chargeable with such conduct, particularly provoke the divine anger. As to little children especially, their helplessness and tender age will even protect them from being attacked by dogs and wild beasts. And what shall we think of the monstrous inhumanity of men, who would make them the objects of their assault? We have here a specimen of the dreadful state of matters which must then have prevailed in the Church of God. The law was there, and the ordinances of divine appointment, yet we see to what an awful extent every species of wickedness abounded. Let us beware lest we fall into a similar state of corruption, and should it so happen under our own observation that men persecute the stranger, seize the widow, and rob the fatherless, let us, in imitation of the Psalmist, who would have us alleviate their misfortunes, pray God to undertake their defense.

They break in pieces thy people - They tread down; they grind; they crush. The Hebrew word is often used as meaning to crush under foot; to trample on; and hence, it means to oppress. Lamentations 3:34; Isaiah 3:15.
And afflict - To wit, by oppression and wrong. If this refers to foreigners, it means that they did this by invasion and by the ravages of war.
Thine heritage - Thy people, regarded as an inheritance or possession. See Psalm 28:9, note; Psalm 33:12, note; Psalm 68:9, note; Psalm 74:2, note; Isaiah 19:25, note; Isaiah 47:6, note; 1-Peter 5:3, note.

They break in pieces thy people - This was true af the Babylonians. Nehuchadnezzar slew many; carried the rest into captivity; ruined Jerusalem; overturned the temple; sacked, pillaged, and destroyed all the country.

They (d) break in pieces thy people, O LORD, and afflict thine heritage.
(d) Seeing the Church was then so sore oppressed, it ought not to seem strange to us, if we see it so now, and therefore we must call to God, to take our cause in hand.

They break in pieces thy 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 thine 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.

thy people [and] thine heritage--are synonymous, the people being often called God's heritage. As justice to the weak is a sign of the best government, their oppression is a sign of the worst (Deuteronomy 10:18; Isaiah 10:2).
