'Needful' in the Bible

The rest of the things required for the house of your God, which you may have occasion to provide, provide it from the royal treasury.

Keep deception and lies far from me;Give me neither poverty nor riches;Feed me with the food that is my portion,

But He was wounded for our transgressions,He was crushed for our wickedness [our sin, our injustice, our wrongdoing];The punishment [required] for our well-being fell on Him,And by His stripes (wounds) we are healed.

yet to remain in my body is more necessary and essential for your sake.
