Charles H. Spurgeon on Psalms 44:20

An appeal is now made to the omniscience of God; he is himself called in to bear witness that Israel had not set up another God. If we have forgotten the name of our God. This would be the first step in apostasy; men first forget the true, and then adore the false. Or stretched out our hands to a strange god. Stretching out the hands was the symbol of adoration or of entreaty in prayer; this they had not offered to any of the idols of the heathens.
