Explanatory Notes on the Whole Bible, by John Wesley, [1754-65], at sacred-texts.com
exo 11:2Let every man ask (not borrow!) of his neighbour jewels - This was the last day of their servitude, when they were to go away, and their masters, who had abused them in their work, would now have defrauded them of their wages, and have sent them away empty, and the poor Israelites were so fond of liberty that they themselves would be satisfied with that, without pay: but he that executeth righteousness and judgment for the oppressed, provided that the labourers should not lose their hire. God ordered them to demand it now at their departure, in jewels of silver, and jewels of gold; to prepare for which, God had now made the Egyptians as willing to part with them upon any terms, as before the Egyptians had made them willing to go upon any terms.
exo 11:5The death of the first - born had been threatened, Exo 4:23, but is last executed, and less judgments tried, which, if they had done the work, would have prevented this. See how slow God is to wrath, and how willing to be met in the way of his judgments, and to have his anger turned away! That sitteth upon his throne - That is to set. The maid - servant behind the mill - The poor captive slave, employed in the hardest labour.
exo 11:8All these thy servants - Thy courtiers and great officers: The people that follow thee - That are under thy conduct: and command. When Moses had thus delivered his message, he went out from Pharaoh in great anger, though he was the meekest of all the men of the earth. Probably he expected that the very threatening of the death of the first - born should have wrought upon Pharaoh to comply; especially he having complied so far already, and having seen how exactly all Moses's predictions were fulfilled. But it had not that effect; his proud heart would not yield, no not to save all the first - born of his kingdom. Moses hereupon was provoked to a holy indignation, being grieved, as our Saviour afterwards, for the hardness of his heart, Mar 3:5.
