Ye have shamed the counsel of the poor, because the LORD is his refuge.
Ye have shamed the counsel of the poor - understand, to accord with the first clause of Psalms 14:5, to which this clause is parallel, therefore ye shall be put to shame yourselves. This is elegantly left to be supplied: so certain is the connection between the sin (which is expressed) and its retribution in kind (which is to be understood). Thus the clause tallies with Psalms 53:5, "thou hast put them to shame." Also thus, the "because" follows naturally, ye shall be put to shame for shaming the God-relying counsel of the poor in their trials.
Because the Lord (is) his refuge - parallel to (Psalms 14:5) "God is in the generation of the righteous." As "God" ( 'Elohiym (H430), the mighty, Deity) is "among the righteous," therefore "the Lord ( Yahweh (H3068), in covenant relation with His people) is his (the godly poor man's) refuge."
Closing prayer for Israel's salvation and consequent thanksgiving.
