Charles H. Spurgeon on Psalms 105:37

He brought them forth also with silver and gold. This they asked of the Egyptians, perhaps even demanded, and well they might, for they had been robbed and spoiled for many a day, and it was not meet that they should go forth empty handed. Glad were the Egyptians to hand over their jewels to propitiate a people who had such a terrible friend above; they needed no undue pressure, they feared them too much to deny them their requests. The Israelites were compelled to leave their houses and lands behind them, and it was but justice that they should be able to turn these into portable property. And there was not one feeble person among their tribes —a great marvel indeed. The number of their army was very great and yet there was not one in hospital, not one carried in an ambulance, or limping in the rear. Poverty and oppression had not enfeebled them. JEHOVAH ROPHI had healed them; they carried none of the diseases of Egypt with them, and felt none of the exhaustion which sore bondage produces. When God calls his people to a long journey he fits them for it; in the pilgrimage of life our strength shall be equal to our day. See the contrast between Egypt and Israel —in Egypt one dead in every house, and among the Israelites not one so much as limping.
