Which teacheth thee to profit - Teaching you what things will most conduce to your welfare. The reference hero is chiefly to the afflictions which they suffered in Babylon.
Which leadeth thee - I am thy conductor and guide. God taught them, as he does his people now, by his Providence, his revealed word, and his Spirit, the way in which they ought to go. It is one of his characteristics that he is the guide and director of his people.
