Moses supposes his toeses are roses, but Moses supposes erroneously.
For nobody's toeses are posies of roses as Moses supposes his toeses to be.
Or so says the old children's rhyme, but where in the Bible is this incident of botanical / anatomical confusion recorded?
Well, how about the time when Moses dips his fingers in the blood of a ram and daubs that blood on Aaron and his sons' big toes? [Leviticus 22-24]
That's got to give them a bit of a rosy glow, no?
And why, you might ask, was Moses daubing blood like this in the first place?
To find a rhyme for his name?
No, it was a purification ceremony.
As here, Aaron was purified by the blood of a ram, we can be purified from our sins by the blood of Jesus Christ, the lamb of God.
