     commanded me a business, and hath said unto me, Let no man
     know any thing of the business whereabout I send thee, and
     what I have commanded thee: and I have appointed [my]
     servants to such and such a place.

     (b) These infirmities that we see in the saints of God,

         receives it from God's mercy.

     days, since I came out, and the {d} vessels of the young
     men are holy, and [the bread is] in a manner common, yea,
     though it {e} were sanctified this day in the vessel.

     (d) That is, their bodies.
     (e) Shall be more careful to keep his vessel holy, when he
         has eaten of this holy food.

21:9 And the priest said, The sword of Goliath the Philistine,
     whom thou slewest in the valley of Elah, behold, it [is
     here] wrapped in a cloth behind the {g} ephod: if thou wilt
     take that, take [it]: for [there is] no other save that
     here. And David said, [There is] none like that; give it
     me.

     (g) Behind that place where the high priests garment lay.

      of the gate, and let his spittle fall down upon his beard.

      (i) By making marks and toys.

      (k) Is he fit to be in a king's house.
