Walking among the drops
In the question: Walk with caution so as not to harm anyone and so as not to harm anyone. Speak of things that are considered in the light of knowledge and that are not divided on the basis of knowledge (literally: it remained dry and did not get wet from the rain).
("They said to him, "I have gone," he said to them among the drops of the bodies" - Otzar Hamidrashim (Eisenstein), Ten Proverbs, 461).
