'Joins' in the Bible

You are to make fifty loops along the edge of the end curtain in one set and fifty loops along the edge of the curtain that joins the second set.

This is what everyone who is counted shall give [as he joins those already counted]: a half shekel, according to the sanctuary shekel (the shekel is twenty gerahs); a half shekel as a contribution to the Lord.

Everyone who is counted, from twenty years old and over, [as he joins those already counted], shall give this contribution to the Lord.
