I also heard a sound ¹  coming out of heaven like the sound of many waters and like the sound of loud thunder. Now ²  the sound I heard was like that made by harpists playing their harps,

If, for example, the trumpet makes an unclear sound, who will get ready for battle?

I say this so that no one will deceive you through arguments ¹  that sound reasonable. ² 

But as for you, communicate the behavior that goes with ¹  sound teaching.

For the instant ¹  the sound of your greeting reached my ears, ²  the baby in my womb leaped for joy. ³ 

Suddenly ¹  a sound ²  like a violent wind blowing ³  came from heaven ⁴  and filled the entire house where they were sitting.

sexually immoral people, practicing homosexuals, ¹  kidnappers, liars, perjurers – in fact, for any who live contrary to sound teaching.

Older men are to be temperate, dignified, self-controlled, ¹  sound in faith, in love, and in endurance. ² 

The slave replied, ¹  ‘Your brother has returned, and your father has killed the fattened calf ²  because he got his son ³  back safe and sound.’
