John Calvin Commentary Psalms 35:7

"For without cause have they hid for me their net [in] a pit; Without cause have they digged [a pit] for my soul." — Psalms 35:7 (ASV)

For they have hid for me without a cause. He declares here that he did not take the name of God in vain, nor call upon him for protection without just cause, for he openly asserts his innocence and complains that he was thus severely afflicted without having committed any crime or given any occasion to his enemies.

We should carefully mark this, so that no one may rush rashly into God’s presence, nor call upon him for vengeance, without the assurance and testimony of a good conscience. When he says that he was assailed by stratagem, fraud, and wicked practices, a tacit commendation of his own integrity is implied in this.
