When the Bible says ‘Do not …’

Proverbs 9:8 ⁸ Do not rebuke mockers or they will hate you; rebuke the wise and they will love you.

An example can be found in Matthew 14:3-12, where Baptist John rebuked King Herod.

The following verse teaches us a similar principle.

Proverbs 7:6 ⁶ “Do not give dogs what is sacred; do not throw your pearls to pigs. If you do, they may trample them under their feet, and turn and tear you to pieces.

'what is sacred' and 'pearls' represent 'The Truth of God'.

Then, when does the Bible say 'Do persistently'? Luke 18:1-8 answers 'Prayer'.

Persistent prayer to God will get better result than pressing mockers, dogs, and pigs hard. Let us pray persistently. On the contrary, if we don't pray, we ourselves are in danger to be tempted (this includes being like dogs and pigs) (Matthew 26:41).

And, let us focus on disciple (the wise) training as it is shown in the life of Jesus and Proverbs 9:8^b says "Rebuke the wise and they will love you."
