HEB 4:12

12 [Beware of being insincere about doing this], because the message God [has given us] very powerfully penetrates our thinking more than a two-edged sword [penetrates flesh] [MET]. It penetrates [deeply] into our souls and spirits, as [a sharp sword can penetrate] into our joints and marrow. That [is, by his message God] [PRS] discerns all that we think about, and he discerns all that we desire [to do] [MTY] (OR, [His message] exposes [to us] all our thoughts and all our desires).
