Halakhah su Ezechiele 16:6

"And numerous" - as it is stated (Ezekiel 16:7), "I have given you to be numerous as the vegetation of the field, and you increased and grew and became highly ornamented, your breasts were set and your hair grew, but you were naked and barren;" "And I passed over you and I saw you wallowing in your blood, and I said to you, 'You shall live in your blood,' and I said to you, 'You shall live in your blood'" (Ezekiel 16:6).

If there is to be a bris, it should be performed before Ashrei. The berachah over the circumcision should be said without a cup of wine. In our regions it is customary to say the berachah over the cup of wine, and give a taste of it to the circumcised infant, in addition to what is given to him when saying Bedama'yich cha'yi [In your blood, live] (Ezekiel 16:6). But another child should not be given any of the wine, (for [the laws of Yom Kippur] are more stringent than those of Tishah beAv.) [A mohel] who is accustomed to use wine when doing the metzitzah [sucking blood from the wound] should not spray the wine with his mouth but with his hand, and then suck the blood with his mouth in the usual manner.
