I thought on my ways, and turned my feet unto thy testimonies. First. I thought on my ways - חשבתי chashabti, I deeply pondered them; I turned them upside down; I viewed my conduct on all sides. The word, as used here, is a metaphor taken from embroidering, where the figure must appear the same on the one side as it does on the other; therefore, the cloth must be turned on each side every time the needle is set in, to see that the stitch be fairly set. Thus narrowly and scrupulously did the psalmist examine his conduct; and the result was, a deep conviction that he had departed from the way of God and truth.
Secondly. And turned my feet unto thy testimonies - Having made the above discovery, and finding himself under the displeasure of God, he abandoned every evil way, took God's word for his directory, and set out fairly in the way of life and salvation.
