John Gill Commentary 1 Chronicles 14:2

"And David perceived that Jehovah had established him king over Israel; for his kingdom was exalted on high, for his people Israel`s sake." — 1 Chronicles 14:2 (ASV)

1 Chronicles 14:24

And he shall lay his hand upon the head of the goat
His right hand, as the Targum of Jonathan; (See Gill on Leviticus 1:4)

and kill it ;
not the prince, but the priest after mentioned, or the butcher, as the same Targum:

in the place where they hill the burnt offering before the Lord ;
in the court on the north side of the altar, see (Leviticus 1:11) (6:25) :

it is a sin offering :
an offering for his sin of ignorance, or "sin"; so Christ our offering is said to be, (2 Corinthians 5:21) .
