"And it shall be upon Aaron while officiating, so that the sound of it is heard when he comes into the sanctuary before the LORD and when he goes out – that he may not die." The word 'sound' indicates charity, which is the gematria [numerological] equivalent of 'monies'. They also said: 'Three sounds gladden, the sound of Torah, the sound of money, and the sound of rains' – charity given on Purim, in particular, as it reveals Mordecai's inspiration … This is what I indicated in: 'And it shall be' – that spell the letters of the Name [in Hebrew]. When will the Name of God be completed, Israel redeemed and Aaron called upon to officiate? At the time that 'the sound of it is heard' – hinting at the sound of Torah and the sound of money, both of which hasten the redemption… in particular 'when he comes into the sanctuary' - by the charity, which is called holiness, done on Purim day. It also hints that He will be charitable with Torah scholars, who are called holy; therefore it is certainly the case that 'he goes out', for they cause us to leave the exile - 'that he may not die'.
