The Greek here says, ‘Give the things that are within as alms.’ Some understand this to mean, the things that are within the cup and the things which are placed on the plate, that is, the things which the poor have need of for their sustenance – give alms of these things.
There are those who think that religion can be reduced to the payment of certain outward things to God, while the heart remains free from participation, withheld from him. They treat God as if he could see no further than man can see, and was satisfied with these paltry gifts, while the real person, the inner man, is not included in worship. Can we worship God as he wants when we only worship him with half, or less than half, of our being? Certainly not. Because he made the inner man as well as the outer man, he insists that we worship him with both. Old Testament worship focused on the externals of worship, because it was designed to teach an unspiritual people, the majority of whom were unconverted and incapable of worshipping with the inner man. By teaching them to worship with the outer man, they were being taught the basic principles of worship, but this was never going to be sufficient while their hearts remained alienated from God.
