"and Your Torah to Israel": Agnitis, the general, asked R. Gamliel: How many Toroth were given to Israel. He answered: Two, one written; the other oral.
"They shall place incense before You": This is the inner incense. "and a burnt-offering upon your altar": These are the limbs of the burnt-offering.
(Devarim 33:11) "Bless, O, L-rd, his substance": i.e., his possessions — whence the adage: "Most Cohanim are wealthy." According to Abba the exegete, the verse (Psalms 37:25) "I have been a youth and I have also aged, but I have never seen a tzaddik forsaken nor his children begging for bread" applies to the seed of Aaron.
