"Num. xxxiii. 1. 'Build me here seven alters and prepare me here seven oxen and seven rams.' The ancients were very superstitious about certain numbers, supposing that God delighted in odd numbers.Around his waxen image first I wind Three woollen fillets, of three colours joined; Thrice bind about his thrice devoted head, Which round the sacred alter thrice is led. Unequal numbers please the gods."
