Seek ye the Lord, and be strengthened: seek his face evermore.

“In Psalm 104 [LXX], David, when referring to the stories of Abraham, Isaac and Jacob, the very men who were his godly ancestors, who lived before Moses' day, calls them Christs, only because they all received the outpouring of the Holy Spirit. And when he tells how they were hospitably received by foreigners, and how they learned that God was their Savior when plots were devised against them, following Moses' account, he names them prophets also and Christs, before Moses had been born and before he had laid down the rule that such men should be anointed with oil.”

“"Seek the Lord, and be strengthened" [Psalm 105:4]. This is very literally construed from the Greek, though it may seem not a Latin word: whence other copies have, "be ye confirmed;" others, "be ye corroborated."...While these words, then, "Come unto Him, and be enlightened," apply to seeing; those in the text relate to doing: "Seek the Lord, and be strengthened."...But what means, "Seek His face evermore"? I know indeed that to cling unto God is good for me; but if He is always being sought, when is He found? Did he mean by "evermore," the whole of the life we live here, whence we become conscious that we ought thus to seek, since even when found He is still to be sought? To wit, faith has already found Him, but hope still seeks Him. But love has both found Him through faith, and seeks to have Him by sight, where He will then be found so as to satisfy us, and no longer to need our search. For unless faith discovered Him in this life, it would not be said, "Seek the Lord." Also, if when discovered by faith, He were not still to be diligently sought, it would not be said, "For if we hope for that we see not, then do we with patience wait for it." [Romans 8:25] ...And truly this is the sense of the words, "Seek His face evermore;" meaning that discovery should not terminate that seeking, by which love is testified, but with the increase of love the seeking of the discovered One should increase.”

“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.”
