Thread: in the Bible adjacent psalms usually share at least one striking phrase or concept.

Some from the first 15 Psalms.

Psalm 1:1 begins 'blessed', as does the final line of the next psalm (2:12).

2:6 + 3:4 'holy hill'

3:2 + 4:6 'many are saying'

3:5 + 4:8 'lie down and sleep'

4:2 + 5:6 'falsehood' (כָּזָב)

5:7 + 6:4 'your steadfast love'

6:1 + 7:6 'in your anger' (& loads more between Psalms 6 & 7)

7:5 + 8:2 share the common word 'enemy' (אוֹיֵב), while 6:7; 7:4, 6; 8:2 share the less common word 'foe' (root צרר)

8:1, 9 + 9:2 'your name'

Psalms 9-10 are sometimes considered a single Psalm. They share a rough alphabetic structure + Ps. 10 has no separate heading

The theme of the 'wicked' runs through both, but they also share 'in times of trouble' (9:9; 10:1).

10:8 + 11:4 'his eyes'

11:4 + 12:1, 8 'children of man'

12:5 + 13:2 'I will place' (13:2: lit. 'I will place counsels in my soul')

13:5 'shall rejoice' = 14:7 'let him rejoice' (יָגֵל)

14:1 + 15:2 'in his heart' & contrast of 'evildoers' (14:4) & those who do no evil (15:3)

I hope that's enough to make the point.

Psalms are not randomly arranged.

I've only scratched the surface. There are many connections I haven't listed.

I hope these encourage others to dig deeper.
