Psalms 119:176 - Ellicott's Commentary On The Whole Bible

I have gone astray like a lost sheep. — It would be in accordance with a true religious character that even at the end of a long protestation of obedience to the Divine law the psalmist should confess his weakness and sin. But while this may be a legitimate application of the close of this remarkable composition, and while the LXX. suggest a comparison with our Lord’s parable by their rendering (comp. Matthew 18:11; Luke 19:10), this could hardly have been the intention of the words of this verse. More likely there is a reference to the condition of the community, for the word rendered “lost” (literally, perishing) is used in Isaiah 27:13 of the exiled Hebrews, and is rendered “outcasts;” the emphatic “I do not forget Thy commandments,” which is the real close of the psalm, seems to make this view imperative.
