2 But whose delight is in the law of the Lord, and whose mind is on his law day and night. 3 He will be like a tree planted by the rivers of water, which gives its fruit at the right time, whose leaves will ever be green; and he will do well in all his undertakings.
Matthew Henry's Commentary on Psalm 1:2-3
Commentary on Psalm 1:1-3
(Read Psalm 1:1-3)
To meditate in God's word, is to discourse with ourselves concerning the great things contained in it, with close application of mind and fixedness of thought. We must have constant regard to the word of God, as the rule of our actions, and the spring of our comforts; and have it in our thoughts night and day. For this purpose no time is amiss.
