'Ought' in the Bible

And I wrote this very thing to you, so that, when I came, I wouldn't have sorrow from them of whom I ought to rejoice; having confidence in you all, that my joy would be shared by all of you.

I have become foolish in boasting. You compelled me, for I ought to have been commended by you, for in nothing was I inferior to the very best apostles, though I am nothing.

Behold, this is the third time I am ready to come to you, and I will not be a burden to you; for I seek not your possessions, but you. For the children ought not to save up for the parents, but the parents for the children.
