1. Hear my prayer, O Jehovah ! It is evident that the oppression of his enemies must have been extreme, when David laments his case in such earnest and pathetic terms. The introductory words show that the grief he felt was great. His reason for speaking of the justice and faithfulness of God in connection we have shown elsewhere. Under the term justice, or righteousness, we are not to suppose that he speaks of merit, or hire, as some ignorantly imagine, but of that goodness of God which leads him to defend his people. To the same effect does he speak of God’s truth or faithfulness; for the best proof he can give of his faithfulness is in not forsaking those whom he has promised to help. In helping his people he shows himself to be a just and true God, both in not frustrating their expectation, and in so far as he shows in this extension of mercy what his nature is, that David very properly encourages himself in prayer by making mention of both.
