How long, Lord? - See Psalms 74:1, note; Psalms 74:10, note; and Psalms 77:7-9, notes. This is the language, not of impatience, but of anxiety; not of complaining, but of wonder. It is language such as the people of God are often constrained to employ under heavy trials - trials which continue so long that it seems as if they would never end.
Shall thy jealousy, burn like fire? - That is, Shall it continue to burn like fire? Shall it utterly consume us? On the word jealousy, see the notes at Psalms 78:58.
