SHALL CLEARLY UTTER. Yafli (clearly utter) means to explain and to clarify.

A VOW OF PERSONS. Its meaning is, he will take a vow saying: If God will do the following for me then I will redeem my life in accordance with its value, or the value of my son’s life, or the value of the life of a beast. The kaf of be-erkekha (according to thy evaluation) is, according to all of the grammarians, superfluous. However, there is one who says that the kaf is directed to the kohen. He explains ke-erkekha ha-kohen (v. 12) as, as thou the priest valuest it. He refers to the heh of ha-kohen as a vocative heh. He says that the word, he-erkekha (of thy valuation) (v. 23), is an irregular word. It is like the word ha-oholi (of my tent) in the midst of my tent (Josh. 7:21). However, in my opinion the meaning of ha-oholi is, the tent, mine. Similarly he-erkekha (of thy valuation) (v. 23).
