1 Kings 8:5

And King Solomon, and all the congregation of Israel, that were

On this solemn occasion:

were with him before the ark;
while it was in the court of the priests, before it was carried into the most holy place:

sacrificing sheep and oxen, that could not be told nor numbered for
multitude;
the phrase seems to be hyperbolical, and designed to denote a great number.
