Psalms 4:4

Stand in awe, and sin not: commune with your own heart upon your bed, and be still. Selah.

Proverbs 12:23

A prudent man concealeth knowledge: but the heart of fools proclaimeth foolishness.

Prayers

Lord, I seek to hide Your wisdom in my heart. Help me to remain quiet when it is called for and speak boldly in the proper time. May my countenance speak a word of love in the proper time.
