'Forty four' in the Bible

And I heard the number of the sealed, a hundred and forty-four thousand, sealed out of every tribe of the sons of Israel:

And I saw, and behold, the Lamb standing upon mount Zion, and with him a hundred and forty-four thousand, having his name and the name of his Father written upon their foreheads.

and they sing a new song before the throne, and before the four living creatures and the elders. And no one could learn that song save the hundred and forty-four thousand who were bought from the earth.

And he measured its wall, a hundred and forty-four cubits, a man's measure, that is, the angel's.
