Singing through the Songs of Degrees, morning by morning, I was struck by 132:9 and 16 and pondered on what it actually (in experience and in practice) means . . . .
... thy priests do put on righteousness ... Psalm 132:9 YLT
,... her priests I clothe with salvation ... Psalm 132:16 YLT
Young's Literal does not draw attention in the first text, 132:9, to the clothing but to the act of 'putting on'. The priests - and there is a 'nation of priests' spoken of in scripture, so - many priests who are subject to one great High Priest, passed into the heavens, Jesus the Son of God, Hebrews 4:14 - these priests 'put on' righteousness.
Which reminds me of the exhortation :
... But put ye on the Lord Jesus Christ, and make not provision for the flesh, to fulfil the lusts thereof. Romans 13:14 KJV.
Or, as the literal Greek has it :
... but put on the Lord Jesus Christ and of the flesh do not take forethought unto desire. [EGNT/YLT]
God provided skins for Adam and Eve, after they trangressed and after they discovered their unclothed state. The animal is not mentioned, thus I see that the skin is of something not yet nameable, not yet definable.
It is that which is to come.
And what is to come is another humanity than the humanity that failed in Eden.
Thus, put ye on the Lord Jesus Christ.
This righteousness is not a legal work, but is of love, the fulfilling (by love) of all law for Paul mentions adultery, killing, stealing, lying, and coveting (including both outward acts but also inward desires) the remedy to which he states is the putting on of the Lord Jesus Christ and the working of love to one's neighbour, which bares no ill.
And therein (by 'putting on' the Lord Jesus Christ) is righteousness provided.
Thus God himself speaks in Psalm 132:16, saying, I will clothe her priests with salvation.
Under the headship of Christ, and under the High Priesthood which is his, the members of his body, the priests under his heavenly administration, is received the 'clothing' of righteousness and salvation.
Or is there another meaning to these two texts in Psalm 132 ?
