“But his delight is in the law of the Lord, and in His law he meditates day and night” (Psalms 1:2).
In describing the righteous, the Psalmist indicates their preoccupation with the word of God. They dwell upon it; think about it; ponder it. As a ruminating animal chews, and chews again, its cud, so God’s children continually bring up His word to the forefront of their heart and mind.
It’s something to chew on.
