'Weight' in the Bible

And he took their king's crown from off his head, the weight whereof was a talent of gold with the precious stones: and it was set on David's head. And he brought forth the spoil of the city in great abundance.

And when he polled his head, (for it was at every year's end that he polled it: because the hair was heavy on him, therefore he polled it:) he weighed the hair of his head at two hundred shekels after the king's weight.

The man replied to Joab, “Even if I had the weight of 1,000 pieces of silver in my hand, I would not raise my hand against the king’s son. For we heard the king command you, Abishai, and Ittai, ‘Protect the young man Absalom for me.’

And Ishbibenob, which was of the sons of the giant, the weight of whose spear weighed three hundred shekels of brass in weight, he being girded with a new sword, thought to have slain David.
