For all they did cast in of their abundance,.... Or "superabundance", as the Arabic version renders it; or "superfluity", as the Ethiopic: they abounded in the things of the world, of which they gave only a part; and though they might give much, yet they could easily spare it, and had enough remaining: but she, of her want; or "penury", as in Luk 21:4; see Co2 8:2; did cast in all that she had, even all her living; her whole substance, all that she had in the world; what was to have bought her food, for that day; she left herself nothing, but gave away all, and trusted to providence for immediate supply.
