Now, you have them STANDING or HOLDING the instruments not INSIDE of any holy place. That is because the Levites were under the king and the commanders of the army. Hezekiah was a KING and not a worship leader.
AFTERWARD, Hezekiah took the initiative to offer the goats as a "unity" effort for Israel which had fallen back under the worship of the starry host at Mount Sinai.
Then only during the BURNING of the Goats the Levites made a great NOISE which is never called music.
However, Christ speaks for the SPIRITUAL people and says that God had not COMMANDED burnt offerings when He saved them by grace at the Red Sea. Only AFTER musical idolatry God imposed The Law of Moses but sentenced them to be returned to Babylon for captivity and mostly death. In the meantime God had given them kings in His anger to carry out the WORSHIP OF THE STARRY HOST until they could be removed to Babylon.
So you have the WORSHIP OF THE STARRY host and only after the sacrifices for Judah and Jerusalem did Hezekiah COMMAND what David had commanded. So when they MAKE NOISE you will discover that 2 Chron 29 says that it was by the COMMAND OF DAVID. There are several other parallels. To prove that this was God's ABANDONMENT to paganism and NOT His approved patternism, you can read some Psalms and the prophets for background IN ADDITION to Christ's permissive will to TEAR DOWN the Temple devoted to STAR and SERPENT worship.
This is he, that was in the church in the wilderness with the angel which spake to him in the mount Sina, and with our fathers:
who received the lively oracles to give unto us: Acts 7:38
To whom our fathers would not obey, but thrust him from them,
and in their hearts turned back again into Egypt, Acts 7:39
Saying unto Aaron, Make us gods to go before us: for as for this Moses, which brought us out of the land of Egypt, we wot not what is become of him. Acts 7:40
And they made a calf in those days,
and offered sacrifice unto the idol,
and rejoiced in the works of their own hands. Acts 7:41
This was musical idolatry.
THIS IS WHAT FALSE TEACHERS ARE TRYING TO RESTORE:
Then God turned, and gave them up to worship the host of heaven;
as it is written in the book of the prophets,
O ye house of Israel, have ye offered to me slain beasts
and sacrifices by the space of forty years in the wilderness? Acts 7:42
God had not COMMANDED animal sacrifices to pay for His Grace. However, people LUST to worship the CREATURE.
Yea, ye took up the tabernacle of Moloch,
and the star of your god Remphan,
figures which ye made to worship them:
and I will carry you away beyond Babylon. Acts 7:43
The Tabernacle was a sign of God's presence with them whereever they were and not in HOUSES.
Our fathers had the tabernacle of witness in the wilderness,
as he had appointed, speaking unto Moses,
that he should make it according to the fashion that he had seen. Acts 7:44
Which also our fathers that came after brought in with Jesus into the possession of the Gentiles,
whom God drave out before the face of our fathers,
unto the days of David; Acts 7:45
Who found favour before God,
and desired to find a tabernacle for the God of Jacob. Acts 7:46
But Solomon built him an house. Acts 7:47
Howbeit the most High dwelleth not in temples made with hands; as saith the prophet. Acts 7:48
Heaven is my throne, and earth is my footstool: what house will ye build me? saith the Lord: or what is the place of my rest? Acts 7:49
Stephen told the Jews what is clear in the Old Testament that God cannot be fed, clothed, housed, entertained with music or sexually used as in Jerusalem. The EFFORT people use as a PATTERNISM to say that the "spirit" told them that God commanded THEM to add instrumental praise or they would disobey Him is a flat contradiction of all of the Bible and according to Stephen while Jesus Christ in heaven STOOD UP to bear witness to the truth of Stephen's repudiation of the modern pharisees and Scribes Jesus called hypocrites by naming speakers, singers and instrument players.
Hath not my hand made all these things? Acts 7:50
Ye stiffnecked and uncircumcised in heart and ears,
ye do always resist the Holy Ghost:
as your fathers did, so do ye. Acts 7:51
Sacrifices were restricted to INSIDE of the walls of Jerusalem while the GODLY PEOPLE were "outside the camp" attending synagogue which began in the wilderness to keep the godly people FROM doing what a few evil men are now trying to impose PLANNING to sow discord so they can steal the church houses of widows and honest workers.
Ask: why do legalistic sectarians INSIST on RESISTING the Holy spirit just as did all of those under the Monarchy.
I need a nap but I will show that the command for the warrior's instruments were BY DAVID because the only evidence of God's command was for the two silver trumpets to be BLOWN to signal various events.
