曾子有疾，召门弟子曰，启予足，启予手，诗云，战战兢兢，如临深渊，如履薄冰，而今而后，吾知免夫，小子。

James Legge Translation

The philosopher Tsang being ill, he called to him the disciples of his school, and said, "Uncover my feet, uncover my hands. It is said in the Book of Poetry, 'We should be apprehensive and cautious, as if on the brink of a deep gulf, as if treading on thin ice,' and so have I been. Now and hereafter, I know my escape from all injury to my person, O ye, my little children."
