출애굽기 5:23의 주석

הרע This is an expression denoting “he has caused something to happen” — he (Pharaoh) has brought even more evil upon them. It must be translated in the Targum by אבאיש “he has treated badly”.

והצל לא הצלת, the overseers of the Israelites who are being beaten for showing empathy with the people.

לדבר בשמך…והצל לא הצלת את עמך. "to speak in Your name…but You have not saved Your people." Moses added another argument to his previous ones. He wanted to know how it was possible that since he had spoken to this wicked king in the name of G'd, not only had He not responded but He had actually made things worse for the people whom Moses represented. He emphasised the word מאז to point out that Pharaoh's obstinacy appeared to have been a direct consequece of G'd's intervention through Moses. Clearly what Pharaoh did was motivated by his hatred for G'd. He was unparalleled in his rebellious behaviour against the king of the universe. Moses was amazed at G'd's apparent lack of jealousy of His reputation. Surely G'd now had an additional reason to redeem Israel immediately. Even if Israel did not merit redemption at this time due to its own merit, it had to be redeemed as a gesture against the blaspheming Pharaoh! The words והצל לא הצלת should be read as a question expressing Moses' amazement that G'd had not yet saved His people. Moses spoke of two "salvations," i.e. the one due to Israel's merit and the one due to Pharaoh's excesses.
