'Corner' in the Bible

On Egypt, and on Judah, and on Edom, And on the sons of Ammon, and on Moab, And on all cutting the corner of the beard, Who are dwelling in the wilderness, For all the nations are uncircumcised, And all the house of Israel are uncircumcised in heart!

Behold, the days come, saith the LORD, that the city shall be built to the LORD from the tower of Hananeel unto the gate of the corner.

And the whole valley of the dead bodies, and of the ashes, and all the fields unto the brook of Kidron, unto the corner of the horse gate toward the east, shall be holy unto the LORD; it shall not be plucked up, nor thrown down any more for ever.

They that fled stood under the shadow of Heshbon because of the force: but a fire shall come forth out of Heshbon, and a flame from the midst of Sihon, and shall devour the corner of Moab, and the crown of the head of the tumultuous ones.

And their camels have been for a prey, And the multitude of their cattle for a spoil, And I have scattered them to every wind, Who cut off the corner of the beard, And from all its passages I bring in their calamity, An affirmation of Jehovah.

And they shall not take of thee a stone for a corner, nor a stone for foundations; but thou shalt be desolate for ever, saith the LORD.
