Passage
`Thou dost not commit adultery.
`Thou dost not commit adultery.
Exodus 20:12 `Honour thy father and thy mother, so that thy days are prolonged on the ground which Jehovah thy God is giving to thee.
Exodus 20:13 `Thou dost not murder.
Exodus 20:14 `Thou dost not commit adultery.
Exodus 20:15 `Thou dost not steal.
Exodus 20:16 `Thou dost not answer against thy neighbour a false testimony.
The verse centers on "thou", "dost", "commit", and "adultery". It is saying that the verse draws attention to "thou" and "dost", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "Thou dost not murder..." into verse 15's "Thou dost not steal...", so "thou" and "dost" belong inside that flow. In Exodus context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "thou" and "dost" with trust shaped by these words, not by a vague optimism outside the passage.
