Last night I was reading through the New American Standard version of the Psalms, and discovered these verses, all of which suggest a spirituality of contemplation and silent resting/waiting for God:
Tremble, and do not sin;
Meditate in your heart upon your bed, and be still. Selah.
— Psalm 4:4
Rest in the LORD and wait patiently for Him;
Do not fret because of him who prospers in his way,
Because of the man who carries out wicked schemes.
— Psalm 37:7
My soul, wait in silence for God only,
For my hope is from Him.
— Psalm 62:5
There will be silence before You, and praise in Zion, O God,
And to You the vow will be performed.
— Psalm 65:1
Surely I have composed and quieted my soul;
Like a weaned child rests against his mother,
My soul is like a weaned child within me.
— Psalm 131:2
