“And if his offering is of the flocks – of the sheep or of the goats – as a burnt sacrifice, he shall bring a male without blemish. He shall kill it on the north side of the altar before the Lord; and the priests, Aaron’s sons, shall sprinkle its blood all around on the altar.” Leviticus 1:10-11.
“In the year that King Uzziah died, I saw the Lord sitting on a throne, high and lifted up, and the train of His robe filled the temple. Above it stood seraphim; each one had six wings: with two he covered his face, with two he covered his feet, and with two he flew. And one cried to another and said: ‘Holy, holy, holy is the Lord of hosts; the whole earth is full of His glory!’ And the posts of the door were shaken by the voice of him who cried out, and the house was filled with smoke.” Isaiah 6:1-4.
“If you endure chastening, God deals with you as with sons; for what son is there whom a father does not chasten? But if you are without chastening, of which all have become partakers, then you are illegitimate and not sons. Further, we have had human fathers who corrected us, and we paid them respect. Shall we not much more readily be in subjection to the Father of spirits and live? For they indeed for a few days chastened us as seemed best to them, but He for our profit, that we may be partakers of His holiness.” Hebrews 12:7-10.
