I never thought of the idea of a curse being a part of prayer. I had to take a second look.

“Whoever curses his father or his mother is to be put to death.” – Exodus 21:17 GNT

In this case, the idea is that a child who threatened their parents with a death threat would suffer the consequences.

“Since to curse was to will and pray the downfall of the other with all one’s heart, it represented the attitude from which sprang acts like striking or murder.” – Cole

Paul has a prayer example on how to bless.

And God, who supplies seed for the sower and bread to eat, will also supply you with all the seed you need and will make it grow and produce a rich harvest from your generosity. He will always make you rich enough to be generous at all times, so that many will thank God for your gifts which they receive from us. – 2 Corinthians 9:10-11 GNT

Paul recognizes that God supplies all of our needs. Whatever I have was given to me by God.

“Our translators render it in the form of a prayer; which yet being the prayer of the apostle, put up in faith, doth virtually contain a promise both of a temporal and a spiritual increase.” – Poole 

This is not only a prayer of blessing that they may give, but also that they may be able to give at all times. Those funds coming from God’s favour on the work of our hands. I think the idea here is not just material wealth but spiritual as well. For it takes a spiritual person to be able to continue to give once they have experienced wealth.

“No man ought to live to himself; the two great ends of every Christian’s life ought to be, the glory of God, and the good of others, especially such as belong to the household of faith.” – Poole

The direction of thanksgiving in all of this goes to God.

The first rule is completely counterintuitive. Augustine wrote that before anyone can turn to the question of what to pray and how to pray it, he or she must first be a particular kind of person. What kind is that? He writes: “You must account yourself ‘desolate’ in this world, however great the prosperity of your lot may be.” He argues that no matter how great your earthly circumstances, they cannot bring us the peace, happiness, and consolation found in Christ. The scales must fall from our eyes. If we don’t see that truth, all our prayers will go wrong. – Timothy Keller
