Let's start with 1 Chronicles 29:14 - David here is referring to the generosity of his people when donating to the temple that Solomon will build. Part of that passage reads like this:
"But who am I, and who are my people, that we should be able to give as generously as this? Everything comes from you, and we have given you only what comes from your hand.
We understand here, that everything we have is not ours but a gift from God to use as he directs.
In the first chapter of Nehemiah, we find Nehemiah greatly distressed at the condition of Jerusalem, this culminates with him praying and fasting earnestly to the Lord. With God's favor he then boldly asked King Artaxerxes (a non-believer and the major world leader of his day) for a significant material donation and permission to do the work restoration work God put onto his heart.
In Luke Ch 8:1-2 we are introduced to some of Jesus's disciples, great women of faith it is here we learn how Jesus' own ministry was funded. Jesus was supported by precious gifts from these faithful women and "many others."
God's miraculous provision for the needs of others is often in Him giving though us.
