'Meditation' in the Bible

{To the chief Musician upon Nehiloth, A Psalm of David.} Give ear to my words, O LORD, consider my meditation.

Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O LORD, my strength, and my redeemer.

My mouth shall speak of wisdom; and the meditation of my heart shall be of understanding.

My meditation of him shall be sweet: I will be glad in the LORD.

MEM. O how love I thy law! it is my meditation all the day.

I have more understanding than all my teachers: for thy testimonies are my meditation.
