'Point' in the Bible

And Esau said, Behold, I am at the point to die: and what profit shall this birthright do to me?

And this shall be your north border: from the great sea ye shall point out for you mount Hor:

From mount Hor ye shall point out your border unto the entrance of Hamath; and the goings forth of the border shall be to Zedad:

And ye shall point out your east border from Hazarenan to Shepham:

The sin of Judah is written with a pen of iron, and with the point of a diamond: it is graven upon the table of their heart, and upon the horns of your altars;

I have set the point of the sword against all their gates, that their heart may faint, and their ruins be multiplied: ah! it is made bright, it is wrapped up for the slaughter.
