Charles H. Spurgeon on Psalms 55:2

In my complaint. The word here employed commonly means discourse, meditation. It here occurs in the sense of complaint, as in Job 7:13 9:27 21:4 23:2 Ps 142:2 1Sa 1:16. It is not used, however, to denote complaint in the sense of fault finding, complaining, accusing, or the idea that we have been dealt with unjustly. This is not the meaning in this place or in the Scriptures generally. It is the language of a troubled, not of an injured spirit. Albert Barnes, 1868.
