"I haven’t gone astray from your precepts" (119:110), but the last verse says, "I have gone astray like a lost sheep" (119:176). Which is it?

The psalm says both, and it says them with the same Hebrew verb, ta'ah (tap astray): lo ta'iti, I have not strayed, in 119:110, and ta'iti, I have strayed, in 119:176. It says more of the same kind. "Before I was afflicted, I went astray; but now I observe your word" (119:67), with another verb, shagag. It prays, "Don’t let me wander from your commandments" (119:10), with a third, shagah. And it says, "I have done what is just and righteous" (119:121). Even the last verse holds both together: "I have gone astray like a lost sheep. Seek your servant, for I don’t forget your commandments" (119:176). The psalm doesn't say how the two fit, and these notes don't add an explanation. What it does is end with a request: "Seek your servant" (119:176).
