'Bought' in the Bible

So I bought the waistband according to the word of the Lord and put it on my loins.

“Get up and take the waistband that you have bought, which is [wrapped] around your loins, and go to the [river] Euphrates and hide it there in a crevice of the rock.”

“I bought the field that was at Anathoth from Hanamel my uncle’s son, and weighed out the money for him, seventeen shekels of silver.

Fields will be bought in this land of which you say, “It is desolate, without man or animal; it is given into the hands of the Chaldeans.”
