‘The meditation on history is here worked out in detail with an eye on the incomprehensible fact that the tribe of Joseph (v.9), the eyewitness of the mighty saving acts at the time of Moses (v.11) and the first bearer of the covenant which God made with the people at Sinai (v.10), has not remained faithful to God.’
–Artur Weiser The Psalms (Philadelphia: Westminster, 1962 E.T. of 1959 German original), p. 539
