This word appears only one time in all of scripture. It is God himself speaking it. Modern Church has long ditched it.
Remember this, and become men: bring it again to mind, O ye transgressors.
Isaiah 46:8 Literal
The verb is in the Hithpo’el form which is a reflexive verb form that literally means “to become a man”. This isn’t God giving a pep talk. You are an animal, a creature on all fours, so long as you are not walking upright. Some people are doubled over for a long time. That is exactly what it is like to be under the burden of sin. The only way to be set free and become a man is to die to the law of sin and death. Stop trying to follow rules. Learn wisdom.
