JMNT(i)
23 Because if someone is a hearer of [the] Word (a listener to a thought, idea or message) and not a doer (performer; producer), this one is like (resembles) an adult male contemplating (considering; attentively pondering) in a mirror the face of his birth (genesis; origin; existence; generation; lineage; or: = the face with which he was born):
24 for he contemplated himself and has departed, and immediately forgot of what sort (quality; manner) he was.
25 But the one stooping down beside in order to attentively view into (giving a penetrating look into) the perfect (finished and realized; matured; completed; full-grown and fully developed; purposed and destined) law – the one which is freedom (or: the one whose source is, and which has the qualities of, freedom and liberty) – and then remaining (abiding; dwelling) beside [it] – not being birthed (or: coming to be) a hearer of forgetfulness (or: a forgetful listener), but rather a performer of work (a producer of action) – this person will continue being happy and blessed within his performing and in union with his producing.
