'Fifty' in the Bible

You shall count fifty days to the day after the seventh sabbath; then you shall present a new grain offering to the Lord.

If your valuation is of the male from twenty years even to sixty years old, then your valuation shall be fifty shekels of silver, after the shekel of the sanctuary.

‘Again, if a man consecrates to the Lord part of the fields of his own property, then your valuation shall be proportionate to the seed needed for it: a homer of barley seed at fifty shekels of silver.
