Passage
He hath put forth his hands against such as be at peace with him: he hath broken his covenant.
He hath put forth his hands against such as be at peace with him: he hath broken his covenant.
Psalms 55:18 He hath delivered my soul in peace from the battle that was against me: for there were many with me.
Psalms 55:19 God shall hear, and afflict them, even he that abideth of old. Selah. Because they have no changes, therefore they fear not God.
Psalms 55:20 He hath put forth his hands against such as be at peace with him: he hath broken his covenant.
Psalms 55:21 The words of his mouth were smoother than butter, but war was in his heart: his words were softer than oil, yet were they drawn swords.
Psalms 55:22 Cast thy burden upon the LORD, and he shall sustain thee: he shall never suffer the righteous to be moved.
The verse centers on "hath", "forth", "hands", "against", "such", "peace", and "broken". It is saying that the verse draws attention to "hath" and "forth", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 19's "God shall hear and afflict them even..." into verse 21's "The words of his mouth were smoother...", so "hath" and "forth" belong inside that flow. In Psalms context, the local focus is worship, trust, the LORD's kingship, and covenant mercy.
A plain takeaway is to answer the verse's own emphasis on "hath" and "forth" with trust shaped by these words, not by a vague optimism outside the passage.
