'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 lo! the Lamb, standing upon the mount Zion, - and, with him, a hundred and forty-four thousand, having his name and his Father's name written upon their foreheads.

And they sing as it were a new song before the throne, and before the four living creatures and the elders. And, no one, was able to learn the song, save the hundred and forty-four thousand, who had been redeemed from the earth.

And he measured the wall thereof, - a hundred and forty-four cubits: the measure of a man, which is the measure of a messenger.
