Joel chapter 2, Acts chapter 2, and of course Corinthians about the gifts of the Spirit that come from it.
Out of our bellies (innermost being) shall flow living waters, and this lines up with the pattern in that there was a river running under the temple which the priests used to wash the sacrifice blood away. It is this river in us that washes away the things of the blood of Adam, and sets us free.
The tabernacle in Hebrews 10 it is said is the pattern of heavenly things, so it follows if you want to comprehend heavenly realities, you must study the tabernacle. As such, there is saved (outer court) and there is sanctified (inner court). The baptism in the HG begins our sanctification process.
It is as water cleanses (outer court), but fire (inner court) sterilizes, in the natural application. And this is why they received the baptism of the HG on the day of Pentecost as tongues of fire upon their heads. The soul is the candle of the Lord, and on the day of Pentecost, He "lit" His candles.
