121. I have done judgment and righteousness. The Prophet implores the help of God against the wicked who troubled him, and he does so in such a manner as at the same time to testify that the harassing treatment he received from them was on his part altogether undeserved. If we would have God to come down to succor us, it becomes us to see to it that we meet him with the testimony of a good conscience. As He everywhere promises his aid to the afflicted who are unrighteously oppressed, it is no superfluous protestation which the Prophet makes, that he had not provoked his enemies, but had restrained himself from all injury and wrong-doing, and had not even attempted to requite evil for evil. In asserting that he had at all times done judgment, he means that whatever rite wicked practiced, he steadfastly persevered in following after integrity, and never turned aside from what was just and right in any of his public or private transactions.
