'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 a male between twenty and sixty years of age, then your valuation shall be fifty shekels of silver, according to the shekel of the sanctuary.

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