And Yehuda approached him... (Bereshit 44:18)

Said Rabbi Yehuda: The verb "he approached" (vayigash) implies an approach to battle, as in the verse (II Samuel 10:13), "So Joab and the people that were with him approached unto battle."
Rabbi Nechemiah said: The verb "he approached" implies a coming near for conciliation, as in the verse (Joshua 14:6), "Then the children of Yehuda approached Joshua."
The Sages said: It implies coming near for prayer, as in the verse (I Kings, 18:36), "And it came to pass at the time of the evening offering, that Elijah the prophet approached..."
Rabbi Eleazar combined all these views: Yehuda approached Joseph for all three, saying: If it be war, I approach for war; if it be conciliation, I approach for conciliation; if it be for entreaty, I approach to entreat.
