Yĕsha‘ăyāhû (Isaiah) 30:18

But as for you, continue in what you have learned and have firmly believed, knowing from whom you learned it and how from childhood you have been acquainted with the sacred writings which are able to instruct you for salvation through faith in Christ Jesus.

2 Timothy 3:14–15

O Prophet, when you divorce women, divorce them when they have reached their period. Count the period, and fear God your Lord. Do not expel them from their houses, nor let them go forth, except when they commit a flagrant indecency. Those are God's bounds; whosoever trespasses the bounds of God has done wrong to himself. Thou knowest not, perchance after that God will bring something new to pass.
