What is "ha'Avarah"?
Rashi: It is a ferry to cross the river.
Radak: It is a company of people. Kli Yakar - they would carry the women and children across on their shoulders 1 (refer to 19:19:3:1).
Perhaps the women sat in carriages or chairs resting on poles on the men's shoulders. Or, Kadosh men carried the women directly on their shoulders. Rav Acha said 'also you may dance with the Kalah on your shoulders, if she is like a log to you' (Kesuvos 17a). (PF).
What is the meaning of "La'avir"?
Radak: It is like Leha'avir. Also "Lashmid" (Yeshayah 23:11) is like Lehashmid.
Who is "Beis ha'Melech"?
Radak: It is the women and children who cannot walk across.
Why does it say "La'asos ha'Tov b'Einav"?
Malbim: They did not stipulate with him that they return him on condition that he pardon all who sinned against him, like is normal after a rebellion. Rather, they accepted subservience to him, however he will want to pardon or punish. This aroused Shim'i to ask for pardon.
When did Shim'i fall in front of David?
Radak: It is when David came to cross. Malbim - he had to request now, when David was still like a commoner. After he crosses, he is a king, who cannot pardon his honor 1 even b'Di'eved (Kesuvos 17a)!
David pardoned Shim'i when he first cursed him! We can say that also then, David was like a commoner. However, Shlomo was king when he pardoned Adoniyahu! This requires investigation. (PF)
