* On foot: The most likely method of travel, especially considering their circumstances. They were poor widows, likely without resources to hire transportation.
* By donkey: It's possible they may have owned or borrowed a donkey for carrying their belongings and easing the journey, particularly for Naomi who was older.
* By walking alongside a caravan: This would have provided some safety and companionship, especially for a woman traveling alone.
Ultimately, the Bible focuses on the emotional and spiritual journey of the two women, not the specifics of their physical travel.
