Psalms 55:19

“God shall hear and afflict them, etc.] That is, either he shall hear the prayers of his servant, imprecating evils upon his enemies, (<195509>Psalm 55:9,15); and shall bring them down upon them, in answer to his requests; or it may be, rendered, “God shall hear and answer them” f727; he shall hear their blasphemies, and take notice of their wickedness, and answer them by terrible things in righteousness; even he that abideth of old; or “is the inhabitant of eternity” f728 (<235715>Isaiah 57:15); the eternal God, from everlasting to everlasting, who was before all creatures and before all time, and will ever remain the same, out of whose hands there is no escaping. The Targum is, “and he…”

“God hears the wicked in wrath. abideth--or, "sitteth." of old--enthroned as a sovereign. Because . . . no changes--Prosperity hardens them (Psa 73:5).”

“God shall hear and afflict them - That is, God will hear my prayer, and will afflict them, or bring upon them deserved judgments. As this looks to the future, it would seem to show that when in the previous verse he uses the past tense, and says that God “had” redeemed him, the language there, as suggested above, is that of strong confidence, implying that he had such certain assurance that the thing would be, that he speaks of it as if it were already done. Here he expresses the same confidence in another form - his firm belief that God “would” hear his prayer, and would bring upon his enemies deserved punishment. Even he that abideth of old - The eternal God; he who is from everlasting.…”

“Hear - My prayers. Eternity - Who is eternal, and therefore unchangeable, and almighty. Because - They meet with no crosses nor disappointments. Therefore - Their success makes them go on securely, without any regard to God, or dread of his judgments. Psalms 55:20”

“55:19-21 God is good and faithful, but the psalmist’s enemies and so-called friend are deceitful and wicked.”
