Epibibazō means to cause someone to mount or get onto an animal — to lift another person up and place them on a horse or donkey. It appears 3 times in the NT, always in the context of a person being placed on a riding animal by someone else.
The Good Samaritan "put him [epibibasas] on his own donkey" (Luke 10:34). This small detail is theologically loaded: the Samaritan not only pays for care, but physically lifts the wounded man, places him on his own animal, and walks beside him. This is incarnational service — costly, personal, sacrificial proximity to the suffering. The parable is not primarily about ethics but about the nature of neighborly love — and ultimately, about Christ who comes to us in our helplessness, lifts us up, and carries us to safety at His own expense.
