Exodus 16:13-21
In the evening quail came up and covered the camp, and in the morning dew lay around the camp. And when the dew had gone up, there was on the face of the wilderness a fine, flake-like thing, fine as frost on the ground. When the people of Israel saw it, they said to one another, “What is it?” For they did not know what it was. And Moses said to them, “It is the bread that the Lord has given you to eat. This is what the Lord has commanded: ‘Gather of it, each one of you, as much as he can eat. You shall each take an omer, according to the number of the persons that each of you has in his tent.’” And the people of Israel did so. They gathered, some more, some less. But when they measured it with an omer, whoever gathered much had nothing left over, and whoever gathered little had no lack. Each of them gathered as much as he could eat. And Moses said to them, “Let no one leave any of it over till the morning.” But they did not listen to Moses. Some left part of it till the morning, and it bred worms and stank. And Moses was angry with them. Morning by morning they gathered it, each as much as he could eat; but when the sun grew hot, it melted. (ESV)
2 Corinthians 8:1-15
We want you to know, brothers, about the grace of God that has been given among the churches of Macedonia, for in a severe test of affliction, their abundance of joy and their extreme poverty have overflowed in a wealth of generosity on their part. For they gave according to their means, as I can testify, and beyond their means, of their own accord, begging us earnestly for the favor of taking part in the relief of the saints— and this, not as we expected, but they gave themselves first to the Lord and then by the will of God to us. Accordingly, we urged Titus that as he had started, so he should complete among you this act of grace. But as you excel in everything—in faith, in speech, in knowledge, in all earnestness, and in our love for you—see that you excel in this act of grace also.
I say this not as a command, but to prove by the earnestness of others that your love also is genuine. For you know the grace of our Lord Jesus Christ, that though he was rich, yet for your sake he became poor, so that you by his poverty might become rich. And in this matter I give my judgment: this benefits you, who a year ago started not only to do this work but also to desire to do it. So now finish doing it as well, so that your readiness in desiring it may be matched by your completing it out of what you have. For if the readiness is there, it is acceptable according to what a person has, not according to what he does not have. For I do not mean that others should be eased and you burdened, but that as a matter of fairness your abundance at the present time should supply their need, so that their abundance may supply your need, that there may be fairness. As it is written, “Whoever gathered much had nothing left over, and whoever gathered little had no lack.” (ESV)
Mark 12:41-44
And he sat down opposite the treasury and watched the people putting money into the offering box. Many rich people put in large sums. And a poor widow came and put in two small copper coins, which make a penny. And he called his disciples to him and said to them, “Truly, I say to you, this poor widow has put in more than all those who are contributing to the offering box. For they all contributed out of their abundance, but she out of her poverty has put in everything she had, all she had to live on.” (ESV)
