'Becometh' in the Bible

And to Jonathan son of Saul is a son -- lame; he was a son of five years at the coming in of the rumour of the death of Saul and Jonathan, out of Jezreel, and his nurse lifteth him up, and fleeth, and it cometh to pass in her hasting to flee, that he falleth, and becometh lame, and his name is Mephibosheth.

and the salvation on that day becometh mourning to all the people, for the people hath heard on that day, saying, 'The king hath been grieved for his son.'

Of the three is he not the honoured? and he becometh their head; and unto the first three he hath not come.
