The king was to have a special interest in the welfare of the weakest and most vulnerable members of society. The ruler’s power and authority are given to him by God to exercise on behalf of those who lack power.
Such compassion characterises the King of kings and Lord of lords, and is characteristic of his kingdom on earth (Psalm 72:13). This kingdom is of course the New Testament church. It must be a place where the poor and needy can find a refuge. The church must be an example to the world of how to care for its own, even though they are weak. Therefore they must often ask about each other’s welfare and be ready to distribute help as required. This should be done both by individuals and by the leadership of the church. Paul gives Timothy instructions on how to go about this in relation to one class of needy person (1 Timothy 5:3-16), and provision for the poor was a constant concern of the apostles (Galatians 2:10). But that practical provision is just one expression of a love that ought to express itself in many ways among God’s people. It will give whatever is needed, be it food, shelter, clothing, or a word of encouragement, a word of instruction, or even a word of correction.
