Psalms 119:9 - Coke's Commentary on the Holy Bible

Wherewithal shall a young man— Or, Wherewith shall a young man cleanse his way, that he may observe thy word? The original word זכה zakkah, rendered, cleanse, signifies to make clean, purify. See Psalms 73:13. 2 Samuel 11:4. But, on the whole, I consider our version as more elegant than the other given above, because it contains a fine and satisfactory answer to the question in the former clause. Have I hid, in the 11th verse, signifies, treasured up, like something of inestimable value: it may be read, Have I laid up within, &c.
