The captains execute the orders of Jehoiada exactly as they have been told. We see here that captains over others can only act well if they themselves are obedient to those who are above them (cf. Mt 8:99For I also am a man under authority, with soldiers under me; and I say to this one, ‘Go!’ and he goes, and to another, ‘Come!’ and he comes, and to my slave, ‘Do this!’ and he does [it].”). The men they have under their command are the men who serve or have served “on the sabbath”. The sabbath speaks of the rest of God. Only those who know and participate in the rest of God can be used to protect the king of God.
For us, it means that only believers whose feet are shod “with the preparation of the gospel of grace” (Eph 6:1515and having shod your feet with the preparation of the gospel of peace;) are able to properly protect the honor of Christ. These are the believers who go their way on earth with the peace of God in their hearts, who show in their lives that they are connected with Christ in heaven, as the letter to the Ephesians makes beautifully clear.
The weapons given to the men to defend themselves are not new weapons. These are the old, familiar weapons that King David has already used. As a particularity also is mentioned that they come from the sanctuary. Jehoiada says with this that he is going back to “what was from the beginning” (1Jn 1:11What was from the beginning, what we have heard, what we have seen with our eyes, what we have looked at and touched with our hands, concerning the Word of Life—). He asks, as it were, “for the ancient paths” (Jer 6:1616Thus says the LORD,
“Stand by the ways and see and ask for the ancient paths,
Where the good way is, and walk in it;
And you will find rest for your souls.
But they said, ‘We will not walk [in it].’
). The ancient Word of God is unrivalled in its battle-force. The spears are to kill the enemy, the shields are to protect themselves from the enemy’s counter-attacks.
The weapons with which we must fight are not the weapons of the flesh, but of the Spirit (2Cor 10:3-53For though we walk in the flesh, we do not war according to the flesh,4for the weapons of our warfare are not of the flesh, but divinely powerful for the destruction of fortresses.5[We are] destroying speculations and every lofty thing raised up against the knowledge of God, and [we are] taking every thought captive to the obedience of Christ,). To use them properly, they must come from the presence of the Lord Jesus. They are weapons that have been tested by Him. When we are in His presence we see how He wants us to use the weapons. We then see that the strength for our struggle lies in showing His features.
Thus armed the men stand around the king. The weapons are in their hands, ready for use. The positions they occupy are all connected to the house of the LORD and the altar. For us it means that the spiritual battle is fought in connection with God’s house. The church is closely linked to the Lord Jesus and the truth of this must be defended by us for the sake of Him Who dwells there.
Once that position is taken, the king can come out and be crowned. The crown here is a diadem. The word ‘diadem’ here is the translation of the Hebrew word ‘nezer’. From this word is also derived the Hebrew word translated with ‘Nazarite’. This indicates that the ceremony is more a consecration than a coronation. This is confirmed by the anointing. The kingship of Joash is dedicated to God.
He also receives “the testimony” that is the law, as the guide for his government (Deu 17:14-2014“When you enter the land which the LORD your God gives you, and you possess it and live in it, and you say, ‘I will set a king over me like all the nations who are around me,’15you shall surely set a king over you whom the LORD your God chooses, [one] from among your countrymen you shall set as king over yourselves; you may not put a foreigner over yourselves who is not your countryman.16Moreover, he shall not multiply horses for himself, nor shall he cause the people to return to Egypt to multiply horses, since the LORD has said to you, ‘You shall never again return that way.’17He shall not multiply wives for himself, or else his heart will turn away; nor shall he greatly increase silver and gold for himself.18“Now it shall come about when he sits on the throne of his kingdom, he shall write for himself a copy of this law on a scroll in the presence of the Levitical priests.19It shall be with him and he shall read it all the days of his life, that he may learn to fear the LORD his God, by carefully observing all the words of this law and these statutes,20that his heart may not be lifted up above his countrymen and that he may not turn aside from the commandment, to the right or the left, so that he and his sons may continue long in his kingdom in the midst of Israel.). He must govern in accordance with the Word of God. His ordination happens before God and he is called to live and reign according to the Word of God.
We have nothing else for our stay on earth. The believers now are also “a royal priesthood” (1Pet 2:99But you are a chosen race, a royal priesthood, a holy nation, a people for [God’s] own possession, so that you may proclaim the excellencies of Him who has called you out of darkness into His marvelous light;). We are dedicated, anointed and called to proclaim God’s virtues in the world, and this is only possible if God’s Word is our guide in this. It is not about persuasion or training, but about knowing our position and obedience to live in accordance with that position.
