'Sisters' in the Bible

And his sons have gone and made a banquet -- the house of each in his day -- and have sent and called to their three sisters to eat and to drink with them;

And come unto him do all his brethren, and all his sisters, and all his former acquaintances, and they eat bread with him in his house, and bemoan him, and comfort him concerning all the evil that Jehovah had brought upon him, and they gave to him each one kesitah, and each one ring of gold.
