'Span' in the Bible

It shall be square and folded double, a span in length and a span in width.

It was square; they made the breastpiece folded double, a span long and a span wide when folded double.

Then a champion came out from the armies of the Philistines named Goliath, from Gath, whose height was six cubits and a span.

Remember what my span of life is;For what vanity You have created all the sons of men!

Who has measured the waters in the hollow of His hand,And marked off the heavens by the span,And calculated the dust of the earth by the measure,And weighed the mountains in a balanceAnd the hills in a pair of scales?

“And these are the measurements of the altar by cubits (the cubit being a cubit and a handbreadth): the base shall be a cubit and the width a cubit, and its border on its edge round about one span; and this shall be the height of the base of the altar.

And who of you by being worried can add a single hour to his life?

And which of you by worrying can add a single hour to his life’s span?
