Another matter, “Yitro…heard,” that is what is written: “Cast your bread upon the water, for after many days you will find it” (Ecclesiastes 11:1). Are people imbeciles that they place their bread upon the water? Regarding whom is this stated? It is regarding Yitro, who gave his bread to Moses, as it is stated: “Call him and let him eat bread” (Exodus 2:20). That is, “cast your bread upon the water,” this is Moses, as it is stated: “Because I drew him from the water ” (Exodus 2:10). Why? “For after many days you will find it.” “Aaron and all the elders of Israel came to eat bread” (Exodus 18:12).
