'Didst' in the Bible

And immediately Jesus stretched out his hand and caught hold of him, and says to him, O thou of little faith, why didst thou doubt?

But he answering said to one of them, My friend, I do not wrong thee. Didst thou not agree with me for a denarius?

My head with oil thou didst not anoint, but she has anointed my feet with myrrh.

And why didst thou not give my money to the bank; and I should have received it, at my coming, with interest?
