John Gill Commentary Luke 21:4

"for all these did of their superfluity cast in unto the gifts; but she of her want did cast in all the living that she had." — Luke 21:4 (ASV)

For all these have of their abundance. Which they had remaining; the same Hebrew word (rty) signifying to remain, and to abound. They had large possessions, and gave in much, and yet had a great deal left; out of which they

cast in unto the offerings of God; or "gifts of God". Not as gifts unto him, or among the gifts of God, but into the treasury where the gifts and freewill offerings were put; the same with the "Corban" in (Matthew 27:6). And so the Syriac version here renders it, "the house of the offering of God". And it is expressed in the plural because there were several chests in which these gifts were put for various uses (See Gill on Mark 12:41).

but she of her penury has cast in all the living she had; (See Gill on Mark 12:44).
