Seek the Lord and his strength,.... The ark, which is called his strength, and the ark of his strength, Psa 78:61, because he had shown his great strength by it, in dividing the waters at Jordan, throwing down the walls of Jericho, and plaguing the Philistines because of it, when among them. This was a symbol of God's presence, before which he was sought by his people; and was a type of our Lord Jesus, the man of God's right hand, whom he has made strong for himself, and who is called his strength, Psa 80:18. Some render it, and which Aben Ezra makes mention of, though he rejects it, "seek the Lord in his strength"; or "by it": God is to be sought in Christ; he is the way of access to him. Or the meaning is, seek strength from the Lord; spiritual strength; strength to assist in the exercise of grace, and discharge of duty; seek it from him, in whom are both righteousness and strength. The Septuagint, Vulgate Latin, and Syriac versions, render it, "seek the Lord, and be ye strengthened". The way to gain an increase of spiritual strength is to seek the Lord by prayer, or in his ordinances; see Psa 138:3. The Targum is, "seek the doctrine of the Lord, and his law.'' It follows: seek his face evermore: his favour and lovingkindness; his smiling countenance, which beholds the upright; his gracious presence, and communion with him; which is always desirable, ever to be sought after, and will be eternally and without interruption enjoyed in another world.
