'Needful' in the Bible

And whatsoever more shall be needful for the house of thy God, which thou shalt have occasion to bestow, bestow it out of the king's treasure house.

Remove far from me falsehood and lies; Give me neither poverty nor riches; Feed me with the food that is needful for me:

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.
