And thou shalt put it on a blue lace
The plate of gold:
that it may be upon the mitre;
either the plate or the lace; the lace is the nearest antecedent,
but it seems by what follows it should be the plate:
upon the forefront of the mitre it shall be;
the plate of gold; the mitre was of linen, a wrap of linen about
the head, and was like a turban on it, in the top of it; it did
not come down low upon the forehead, but left that bare for this
plate of gold to be put upon it. Jarchi seems to understand all
this of the lace, by comparing it with the following verse, and (
Exodus
39:31 ) as if the plate was represented as in the lace, and
the lace upon the plate and upon the mitre above; all which he
thinks is to be reconciled by observing, that the plate had three
holes, and in every hole was a blue lace, and each lace was
divided into two parts, so that there were six in all, two laces
at each end of the plate, and two in the middle, by which they
were fastened upon the top of the mitre, by which it was kept
from falling off; and of this middle lace, he thinks, the text is
to be understood. The Targum of Jonathan observes, that this
plate was put on a blue lace, to make atonement for the impudent.
