'Sisters' in the Bible

His sons used to travel to each other's houses in turn on a regular schedule and hold festivals, inviting their three sisters to celebrate with them.

Then all his brothers and sisters and all those who knew him before arrived. They ate food with him in his house, mourned for him, and consoled him for all the trouble that the LORD had brought and placed on him. Some gave him gold bullion and some brought gold earrings.
