II Samuel 23:1-7 An Everlasting Covenant.
In David’s “last words” (v. 1a) as he approached the end of his life, and despite all the great things the LORD for and through him, the thing which stuck out the most for him was that he was privileged to have the Spirit of the LORD speak by him (v. 2). This is why he is remembered as “the sweet Psalmist” (v. 1c). This is also what is meant by him being “the man raised up on high, the anointed of the God of Jacob” (v. 1b). He was raised, as a prophet, to the very council of heaven and there was given the words he spoke and wrote for the canon of holy scripture. He was told that real rulers are those who are “just, ruling in the fear of God” (v. 3). The ruler who heeds God’s word is “like the light of the morning when the sun rises” (v. 4). Sadly, David had to confess that not all his house were as inclined as he was (v. 5a).
For David the covenantal bond with the LORD was everlasting, but some were outward members only – circumcised in body but not in spirit. It is the covenantal bond which “is ordered in all things and secure” (v. 5 Cf. Ch. 7). The covenant is a bond in blood sovereignly administered” (O. Palmer Robertson ‘The Christ Of The Covenants’). For this reason it is everlasting and ordered with a purpose – to include all things and be secure. Our salvation involves the whole of life – all things. It is also secure unto the elect. This is the salvation and desire of all God’s true children. Furthermore, it is a work of God that is ever increasing, as through the word and Spirit we are continually being sanctified. Those outside the covenant, or mere external members, are regarded as “sons of rebellion,” destined for the fire (vv. 6-7).
