Psalm 1:1–3 (ESV)
Blessed is the man
who walks not in the counsel of the wicked,
nor stands in the way of sinners,
nor sits in the seat of scoffers;
2 but his delight is in the law of the Lord,
and on his law he meditates day and night.

3 He is like a tree
planted by streams of water
that yields its fruit in its season,
and its leaf does not wither.
In all that he does, he prospers.

Jeremiah 17:5–8 (ESV);
Thus says the Lord:
“Cursed is the man who trusts in man
and makes flesh his strength,
whose heart turns away from the Lord.
6 He is like a shrub in the desert,
and shall not see any good come.
He shall dwell in the parched places of the wilderness,
in an uninhabited salt land.

7 “Blessed is the man who trusts in the Lord,
whose trust is the Lord.
8 He is like a tree planted by water,
that sends out its roots by the stream,
and does not fear when heat comes,
for its leaves remain green,
and is not anxious in the year of drought,
for it does not cease to bear fruit.”

Philippians 4:6–9 (ESV)
6 do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. 7 And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.
8 Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things. 9 What you have learned and received and heard and seen in me—practice these things, and the God of peace will be with you.
