Joshua 1:7-8

7Only be strong and avery courageous, being careful to do according to all the law bthat Moses my servant commanded you. cDo not turn from it to the right hand or to the left, that you may have good success
Or  may act wisely
wherever you go.
8This Book of the Law shall not depart from your mouth, but eyou shall meditate on it day and night, so that you may be careful to do according to all that is written in it. For then you will make your way prosperous, and then you will have good success.

Psalms 1:1-3

The Way of the Righteous and the Wicked

1 Blessed is the man
The singular Hebrew word for  man (ish) is used here to portray a representative example of a godly person; see Preface

who gwalks not in hthe counsel of the wicked,
nor stands in ithe way of sinners,
nor jsits in kthe seat of lscoffers;
2but his mdelight is in the law
Or instruction
of the Lord,
and on his olaw he meditates day and night.
3 He is like pa tree
planted by qstreams of water
that yields its fruit in its season,
and its rleaf does not wither.
sIn all that he does, he prospers.
