'Showed' in the Bible

Now these are the chief of the mighty men whom David had, who showed themselves strong with him in his kingdom, together with all Israel, to make him king, according to the word of Jehovah concerning Israel.

And David said, I will show kindness unto Hanun the son of Nahash, because his father showed kindness to me. So David sent messengers to comfort him concerning his father. And David's servants came into the land of the children of Ammon to Hanun, to comfort him.
