The Context Behind 1 Corinthians 16:1-2

Then one of them, named Agabus, stood up and predicted by the Spirit that there would be a severe famine throughout the Roman world. This took place during the time of Claudius. So each of the disciples, according to his ability, determined to send relief to the brothers who lived in Judea. This they did, sending it to the elders by means of Barnabas and Saul.

Acts 11:28-30

When James, Cephas, and John, recognized as pillars, acknowledged the grace that had been given to me, they gave the right hand of fellowship to me and Barnabas, [agreeing] that we should go to the Gentiles and they to the circumcised. [They asked] only that we would remember the poor, which I made every effort to do.

Gal 2:9-10

Now about the collection for the saints: you should do the same as I instructed the Galatian churches. On the first day of the week, each of you is to set something aside and save to the extent that he prospers, so that no collections will need to be made when I come. And when I arrive, I will send those whom you recommend by letter to carry your gracious gift to Jerusalem. If it is also suitable for me to go, they will travel with me.

1 Cor 16:1-4

... the churches of Macedonia ... on their own ... begged us insistently for the privilege of sharing in the ministry to the saints....

Now I am giving an opinion on this because it is profitable for you, who a year ago began not only to do something but also to desire it. But now finish the task as well, that just as there was eagerness to desire it, so there may also be a completion from what you have. For if the eagerness is there, it is acceptable according to what one has, not according to what he does not have. It is not that there may be relief for others and hardship for you, but it is a question of equality — at the present time your surplus is [available] for their need, so that their abundance may also become [available] for your need, that there may be equality. As it has been written:

The person who gathered much did not have too much,

and the person who gathered little did not have too little.

Thanks be to God who put the same diligence for you into the heart of Titus. For he accepted our urging and, being very diligent, went out to you by his own choice. With him we have sent the brother who is praised throughout the churches for his gospel ministry. And not only that, but he was also appointed by the churches to accompany us with this gift that is being administered by us for the glory of the Lord Himself and to show our eagerness [to help]. We are taking this precaution so no one can find fault with us concerning this large sum administered by us.

2 Cor 8

Now, however, I am traveling to Jerusalem to serve the saints; for Macedonia and Achaia were pleased to make a contribution to the poor among the saints in Jerusalem.
