Numbers 29:17

And on the second day [ye shall offer] twelve young bullocks, two rams, fourteen lambs of the first year without spot:

Ver. 17. And on the second day ye shall offer twelve, &c.] In every of these seven days sacrifices, one bullock is abated: hereby the Holy Ghost might teach them their duty, to grow in grace and increase in sanctification, that their sins decreasing, the number of their sacrifices, whereby atonement was made for their sins, should also decrease daily. Or it might signify a diminishing and wearing away of the legal offerings, &c., as one well observeth; Hac caeremonia significabat Deus gratiam suam de die in diem crescere, ita nempe ut minuatur vetus homo, et novus augeatur, &c., saith Alsted, - till the very ruins of Satan's castles be, as most of our old castles are, almost brought to ruin.
