'Hem' in the Bible

As Samuel turned around to go, he caught hold of the hem of his robe, and it tore.

And David's men said to him, "Look, today [is] the day about which Yahweh said to you, 'See, I am giving your enemy into your hand, and you can do to him {whatever seems good to you}.'" So David got up and secretly cut the hem of Saul's robe.

{And then} afterward David {felt guilty}, because he had cut {the hem of Saul's robe}.

Now, my father, see, yes, see, the hem of your robe in my hand! For {when I cut} the hem of your robe I did not kill you. Know and {realize} that there is no evil or rebellion in my hand. I did not sin against you, but you [are] hunting down my life to take it.
