The primary Greek word Jesus uses for forgiveness is “aphiemi,” which is formed by “apo,” meaning “from,” and “hiemi,” meaning “to send.”
It’s used 142 times in the New Testament and most of those uses describe actions OTHER than forgiveness.
Mark 1:34 – Jesus drove out demons.
But even in the 45 times it’s used to describe the act of forgiveness, it still retains the sense of releasing something closely held or trapped.
In other words, in order for us to forgive someone there’s a real sense in which we must “release” something.
