my soul--me (Psa 3:2).
Flee--literally, "flee ye"; that is, he and his companion.
as a bird to your mountain--having as such no safety but in flight (compare Sa1 26:20; Lam 3:52).
privily--literally, "in darkness," treacherously.
Literally, "The foundations (that is, of good order and law) will be destroyed, what has the righteous done (to sustain them)?" All his efforts have failed.
temple . . . heaven--The connection seems to denote God's heavenly residence; the term used is taken from the place of His visible earthly abode (Psa 2:6; Psa 3:4; Psa 5:7). Thence He inspects men with close scrutiny.
The trial of the righteous results in their approval, as it is contrasted with God's hatred to the wicked.
Their punishment is described by vivid figures denoting abundant, sudden, furious, and utter destruction (compare Gen 19:24; Job 18:15; Psa 7:15; Psa 9:15).
cup--is a frequent figure for God's favor or wrath (Psa 16:5; Psa 23:5; Mat 20:22-23).
his countenance--literally, "their faces," a use of the plural applied to God, as in Gen 1:26; Gen 3:22; Gen 11:7; Isa 6:8, &c., denoting the fulness of His perfections, or more probably originating in a reference to the trinity of persons. "Faces" is used as "eyes" (Psa 11:4), expressing here God's complacency towards the upright (compare Psa 34:15-16).
