This poor widow hath cast more in ... - That is, more in proportion to her means, and therefore more that was acceptable to God. He does not mean that this was more in value than all which the others had put in but it showed more love to the sacred cause, more self-denial, and, of course, more sincerity in what she did. This is the rule by which God will reward us. Compare 2 Corinthians 8:12.

And he called unto him, his disciples,.... Who were at some little distance from him, he having finished his discourses:

and saith unto them, verily I say unto you: a way of speaking he often used, when he was about to deliver something of importance, and not so easy of belief, and which required attention, and what he solemnly affirmed:

that this poor widow, pointing to her,

hath cast more in, than all they which have cast into the treasury: not that she had cast in more, or so much as any one of them as to value and substance, much less more than them all put together; but that she had cast in more in proportion to what she had, than they had in proportion to their substance; and that hers, though very small in itself, and might be contemptible to others, yet it was more in the account of God and Christ, and more highly valued and esteemed of by them, than all that the rich men put in: since what she gave, she gave in faith, and from a principle of love, and with a view to the glory of God; when theirs was given only in hypocrisy, to make an outward show, and to be seen of men.

This poor widow (ἡ χήρα αὕτη ἡ πτωχὴ)

The Greek order is very suggestive, forming a kind of climax: this window, the poor one, or and she poor.

And he called unto him his disciples, and saith unto them, Verily I say unto you, That this poor widow hath cast more in, than all they which have cast into the treasury:

12:43 Cast more in than all. Note the word more --proportionately, to-wit, to her means, and thus more in the estimation of God, who measures quantity by quality.

12:43 I say to you, that this poor widow hath cast in more than they all - See what judgement is cast on the most specious, outward actions by the Judge of all! And how acceptable to him is the smallest, which springs from self - denying love!

12:41-44 Let us not forget that Jesus still sees the treasury. He knows how much, and from what motives, men give to his cause. He looks at the heart, and what our views are, in giving alms; and whether we do it as unto the Lord, or only to be seen of men. It is so rare to find any who would not blame this widow, that we cannot expect to find many who will do like to her; and yet our Saviour commends her, therefore we are sure that she did well and wisely. The feeble efforts of the poor to honour their Saviour, will be commended in that day, when the splendid actions of unbelievers will be exposed to contempt.
