Exodus 30:32

לא ייסך with two “yods” has the meaning “he shall not do something” (i. e. it is 3rd person masc. sing. Kal), similar to ייטב in (Deuteronomy 6:18) “that it may be well (ייטב) with thee”. על בשר אדם לא ייסך UPON MAN’S FLESH SHALL IT NOT BE POURED — anything from that selfsame oil (which Moses had prepared). ובמתכנתו לא תעשו כמהו AND ACCORDING TO ITS PROPORTION YE SHALL NOT MAKE ANY LIKE IT — In regard to the quantities of its spices ye shall not make any other oil like it — i. e. in regard to the weights of these spices in proportion to the measure of a hin of oil; but if one uses less or more of these spices in proportion to the measure of a hin of oil, it is permitted to do so. And even if it is made in the same proportions as this (the oil made by Moses) it is not the one who anoints himself with it that is punishable (for this applies only to one who anoints himself with the oil made by Moses) but he who compounds it (Keritot 5a). ובמתכנתו is a term denoting amount, as (Exodus 5:8) “the quantity (מתכנת) of bricks”. Similar is the word מתכנת used of the incense (v. 37).

עַל־בְּשַׂ֤ר אָדָם֙ לֹ֣א יִיסָ֔ךְ וּ֨בְמַתְכֻּנְתּ֔וֹ לֹ֥א תַעֲשׂ֖וּ כָּמֹ֑הוּ קֹ֣דֶשׁ ה֔וּא קֹ֖דֶשׁ יִהְיֶ֥ה לָכֶֽם׃

Upon man’s flesh shall it not be poured, neither shall you make any other like it, after the composition of it: it is holy, and holy shall it be for you.
