Psalms 13
Forever? - He had been forgotten so long, and there appeared to be so little prospect of deliverance, that it seemed as if God never would return and visit him with mercy. The expression denotes a state of mind on the verge of despair.
How long - Referring to a second aspect or phase of his troubles. The first was, that he seemed to be “forgotten.” The second referred to here is, that God seemed to hide his face from him, and he asked how long this was to continue.
Wilt thou hide thy face from me - Favour - friendship - is shown by turning the face benignantly toward one; by smiling upon him; in Scriptural language, by “lifting up the light of the countenance” upon one. See the note at Psalm 4:6. Aversion, hatred, displeasure, are shown by turning away the countenance. God seemed to the psalmist thus to show marks of displeasure toward him, and he earnestly asks how long this was to continue.
