Philippians 4:11-13

I don’t say this out of need, for I have learned to be content in whatever circumstances I find myself. I know how to make do with little, and I know how to make do with a lot. In any and all circumstances I have learned the secret of being content ​— ​whether well fed or hungry, whether in abundance or in need. I am able to do all things through him who strengthens me.

Psalm 23:1

The LORD is my shepherd; I have what I need.

1 Timothy 6:6-8

But godliness with contentment is great gain. For we brought nothing into the world, and we can take nothing out. If we have food and clothing, we will be content with these.
