Rabshakeh (see note on 2 Kings 18:16) continues telling the message from the king of Assyria to King Hezekiah's men.

Now in whom are you trusting? Who has given you courage to rebel against me?

The King of Assyria (through his messenger Rabshakeh) does not ask these questions looking for an answer, but wants to make King Hezekiah doubt himself and Egypt's support. (See: rc://en/ta/man/translate/figs-rquestion)

The King of Assyria compares Egypt to a weak walking stick; you expect that it will support you when you lean on it, but instead it breaks and cuts you. (See: rc://en/ta/man/translate/figs-metaphor)
