John Calvin Commentary Psalms 73:2

"But as for me, my feet were almost gone; My steps had well nigh slipped." — Psalms 73:2 (ASV)

As for me, etc. Literally, it is, And I: which should be read with emphasis; for David means that those temptations, which are an affront to the honor of God and overwhelm faith, not only assail ordinary people or those who are endowed with only a small measure of the fear of God, but that he himself, who should have profited above all others in the school of God, had experienced his own share of them.

By presenting himself as an example in this way, he intended more effectively to arouse and incite us to be very watchful over ourselves.

He did not, it is true, actually succumb to the temptation; but, in declaring that his feet were almost gone, and that his steps had well nigh slipped, he warns us that all are in danger of falling, unless they are upheld by the powerful hand of God.
