Calling Before Speaking Teaches the Way of Courtesy

"And He called to Moses" - He set the calling before the speaking. The Torah taught proper conduct [derech eretz], that a person should not say a word to his fellow unless he has first called to him. Rabbi Menassia said: From where do we learn that one who speaks a matter to his fellow is under the rule of "he shall not speak" until his fellow says to him, "Speak"? As it is said, "from the Tent of Meeting, saying" (Leviticus 1:1). This is what Scripture says: "The king has brought me into his chambers" (Song of Songs 1:4) - this is Moses, as it is said, "And He called to Moses." From here they said: any sage who has no discernment, a carcass is better than he. Know that this is so: go and learn from Moses, father of wisdom, father of the prophets, who brought Israel out of Egypt, and miracles were done by his hand - "marvelous works in the land of Ham, terrible things by the Red Sea" (Psalms 106:22) - and he ascended to the heights of heaven and brought down the Torah and busied himself with the work of the Tabernacle; even so he did not enter within until He called to him, as it is said, "And He called to Moses." And elsewhere it says, "And God called to him from the midst of the bush" (Exodus 3:4): at the bush He made a pause between the calling and the speaking, but in the Tent of Meeting there was no pause in it.
