'Gird Yourselves' in the Bible

And David said to Joab and to all the people with him, Tear your clothes and gird yourselves with sackcloth, and mourn before Abner. And King David followed the bier.

Suffer evil, O people, and be broken! And give ear, all from the far places of the earth. Gird yourselves and be broken. Gird yourselves and be broken!
