'Loins' in the Bible

But you, you must gird your loins, and stand, and speak to them all that I command you. {Do not be afraid of them}, or I will shatter you {before} them.

Thus Yahweh said to me: "Go and buy for yourself a loincloth of linen and put it on your loins, but you must not {place} it in water."

So I bought the loincloth according to the word of Yahweh and I put [it] on my loins.

"Take the loincloth that you bought, that [is] on your loins, and stand up, go [to the] Euphrates and hide it there in the cleft of the rock."

For as the loincloth clings to [the] loins of a person, so I caused to cling to me all the house of Israel and all the house of Judah,' {declares} Yahweh, 'to be for me a people, and a name, and a praise, and a glory, but they would not listen.'

Ask please and see whether a male can bear a child. Why [do] I see every strong man [with] his hands on his loins like a woman giving birth? And [why] are all [their] faces changed to paleness?

For [on] every head [is] baldness, and every beard is trimmed. On all [the] hands, slashes, and on [the] loins, sackcloth.
