Many are my persecutors
These "persecutors" are those who run after or pursue. Every believer who stands on the truths of God's word, loves them, defends them, and will not turn away from them is pursued by persecutors. The eyes of persecutors are upon faithful believers at all times desiring not only to intimidate them but also to eventually destroy them, their faith, and their precious word of God.
and mine enemies. The Hebrew word for "enemies" has the basic meaning of "tight, narrow, or in distress." Enemies make the faithful work for God a hardship. They put stumbling blocks before us to make us stumble and fall, lose our testimony, and weaken our influence. These enemies also make war against Christians whether they are true believers or those who only nominally believe. The enemy's desire is to destroy all evidence of the existence of Christian influence in the world and will destroy property, people, and literature in order to do this. Phil. 3:18 (For many walk, of whom I have told you often, and now tell you even weeping, that they are the enemies of the cross of Christ:
yet do I not decline from thy testimonies. The word "decline" carries the idea of reclining or "stretching out." This meaning would indicate that some believers may be lazy in their faithfulness to remain and continue in the word of God, searching the Scriptures, for in them they can find eternal life. Another meaning of the word "decline" means to "thrust away." This would mean that some would turn the Scriptures away from themselves for direction, inspiration, and comfort.But the psalmist here admits that, though the persecutors and enemies may be many, he still remains faithful to the word of God. Even though the comfort and assurance of the word of God seems out of play in our current situation, we need still to remain faithful to reading God's word. The assurance that God's word gives us will come through in due time.
