'Grown' in the Bible

When David had grown very old, they covered him with blankets, but he could not keep warm,

"I'm headed down the road that everyone who lives on earth travels, so be strong and demonstrate that you're a grown man

But he forsook the counsel of the old men, which they had given him, and consulted with the young men that were grown up with him, and which stood before him:

And the young men that were grown up with him spake unto him, saying, Thus shalt thou speak unto this people that spake unto thee, saying, Thy father made our yoke heavy, but make thou it lighter unto us; thus shalt thou say unto them, My little finger shall be thicker than my father's loins.
