'Weight' in the Bible

And he took the crown of their king from his head; it weighed a talent of gold, and [set in it was] a precious stone; and it was placed on David’s head. And he brought the spoil out of the city in great amounts.

When he cut the hair of his head (for at the end of each year he cut it, because its weight was heavy on him) he weighed the hair of his head at 200 shekels by the king’s weight.

Then Ishbi-benob, who was among the descendants of the giant, the weight of whose spear was three hundred shekels (six pounds) of bronze, was armed with a new sword, and he intended to kill David.
