That keep, in mind and heart, that carefully and diligently observe, his testimonies; his precepts. For the reason of this and the other titles of God's word, see the argument or preface to this Psalm. That seek him, to wit, the Lord, expressed Psalms 119:1, that seek his presence, and favour, and acquaintance. With the whole heart; sincerely, industriously, and fervently, above all other things. This is opposed to hypocrisy, and sloth, and lukewarmness in religion.
