Note 1 at 1 Cor. 16:1: Paul is talking about money. There were different types of gifts sanctioned by the example of the first century church.

First, there were gifts given to the poor. That is what Paul is referring to here (cp. with Rom. 15:25-26). In Acts 11:27-30, the saints at Antioch took up an offering for the saints in Jerusalem because of a prophecy given by Agabus the prophet that there would be a drought. Paul was admonished by the apostles in Jerusalem that he was to minister to the poor financially (Gal. 2:9-10) and Paul passed this commandment on to those he ministered to (Acts 20:35; Rom. 12:13; 15:27; 2 Cor. 8-9; 1 Tim. 6:18). There are an abundance of Old Testament scriptures that encourage ministering to the poor with our finances (Lev. 25:35; Dt. 15:7-11; Ps. 41:1-3; Prov. 14:21; 19:17; 22:9; 28:27), and New Testament scriptures (Heb. 6:10; 1 Jn. 3:17) as well as examples (Acts 2:44-45; 4:34-37; 6:1) bare this out.

Paul also made it clear that ministers were to be supported financially by those they minister to (1 Cor. 9:7-14; Gal. 6:6; 1 Tim. 5:17-18). Paul voluntarily exempted himself from this practice in Corinth and Thessalonica (see note 5 at 1 Cor. 9:6, p. 903), but he did receive personal offerings from the Philippians on more than one occasion (Phil. 4:10-19). In the Old Testament, the Lord commanded the Israelites to maintain the priests and Levities (ministers) with their offerings (Dt. 14:27-29; 18:1-2; 2 Chr. 31:4-20).

In verse 6, Paul is soliciting what we would call today a missions offering (see note 2 at v. 6, p. 969). This is what he refers to in Romans 10:15 as those who send.

There is no New Testament example of the believers giving towards building projects. Since the Christians met in homes, this wasn't necessary. However, there are Old Testament examples of the Lord commanding offerings for the construction of the tabernacle (Ex. 25:1-8) and a compulsory offering (tax) for the maintenance of the tabernacle (Ex. 30:11-16).

So there are at least four areas of giving clearly advocated in scripture: (1) giving to the poor, (2) giving to ministers, (3) giving to missions, and (4) giving to pay for facilities.
