'Old' in the Bible

(And Moses [was] {eighty years old}, and Aaron [was] {eighty-three years old} when they spoke to Pharaoh.)

And Moses said, "With our young and with our old we will go; with our sons and with our daughters, with our sheep and goats and with our cattle we will go because [it is] the feast of Yahweh for us."

{Everyone who is counted} from {twenty years old} and above will give the contribution of Yahweh.

[It was] a bekah for the individual, the half shekel according to the sanctuary shekel, for {everyone who was counted}, from {twenty years old} and above, for six hundred and three thousand five hundred and fifty.
