פּירוש אויף בראשית 18:16

וישקיפו [AND THE MEN] GLANCED — Wherever the Hiphil form of שקף occurs in the Scriptures it denotes taking notice for the purpose of bringing evil (Midrash Tanchuma, Ki Tisa 14), except (Deuteronomy 26:15) (a passage dealing with the tithe, including that given to the poor), “Look forth (השקיפה) from thy holy habitation . .. [and bless thy people] for so great is the power (virtue) of giving to the poor that it changes God’s anger into mercy.

ויקומו משם האנשים, two of them went on to Sodom, as we read afterwards ויבואו שני המלאכים סדומה, “the two angels arrived in Sodom” (Genesis 19,1) The senior one of the angels had been the one who had spoken to Avraham. This is implied by the verse וה' אמר המכסה אני מאברהם וגו', “Shall I conceal from Avraham what I am about to do?” in verse 17.

ויקומו משם, from the house of Avraham.

לשלחם means TO ESCORT THEM, for he believed that they were travellers.
