For the LORD God is a sun and shield: the LORD will give grace and glory: no good thing will he withhold from them that walk uprightly.
For the Lord God is a sun and shield. This assigns the reason why the favour of the Lord with poverty and exile is preferable to riches and home without God. For the Lord God ( Yahweh (H3068) 'Elohiym (H430)) is a sun to enlighten (Psalms 27:1; Isaiah 60:19-20; Malachi 4:2; Revelation 21:23), and a shield to protect on all sides. Faith has already laid hold of the answer to the prayer in Psalms 84:9, "Behold, O God our shield."
The Lord will give grace and glory - "grace" now, and "glory" hereafter: as in Christ's case the sufferings come first, accompanied with "grace" to bear them, the "glory" afterward and abidingly. On the contrary, the "glory" of the wicked man's house may now seem "increased," but "his glory shall not descend after him" when he dieth (Psalms 49:16-17).
No good thing will he withhold from them that walk uprightly - in the uprightness of faith (Habakkuk 2:4); in sincerity toward God and integrity toward man (Psalms 15:2).
