Isaías 66:2
"For heaven is his resting place and the earth his footstool," because on the earth he conversed in the flesh with men and women. And the sacred flesh of God has been called his foot. The church, too, is called the place of God, because we have set it apart for the glorifying of God as a sort of consecrated place wherein we also hold conversation with him. Likewise also the places in which his energy becomes manifest to us, whether through the flesh or apart from the flesh, are spoken of as the places of God. — ORTHODOX FAITH 1:13
Isaías 66:7
Now when the fullness of time came, an angel of the Lord was sent to [Mary] with the good news of her conception of the Lord. And thus she conceived the Son of God, the subsistent power of the Father, "not of the will of the flesh or of the will of man"—that is to say, not of carnal conjunction and seed—but of the good pleasure of the Father and the cooperation of the Holy Spirit. To the Creator she gave that he might be created, to the Fashioner that he might be fashioned, and to the Son of God and God that he might from her innocent and undefiled flesh and blood put on flesh and become man. And thus she paid the debt for the first mother. For as Eve was formed from Adam without carnal conjunction, so did this one bring forth the new Adam in accordance with the law of gestation but surpassing the nature of generation. Thus, he who is without a mother begotten of a father was without a father born of a woman. And because it was of a woman it was in accordance with the law of gestation; while, because it was without father, it surpassed the nature of generation. And because it was at the normal time, for having completed the nine-month period he was born at the beginning of the tenth, it was in accordance with the law of gestation, while because it was without pain it surpassed the established order of birth—for where pleasure had not preceded, pain did not follow, as the prophet said, "Before she was in labor, she brought forth," and again, "before her time came to be delivered she brought forth a man child."And so the Son of God became incarnate and was born of her. It was not as God-bearing man that he was born of her but as God incarnate; not as a prophet anointed through the operation of the one anointing but as one anointed with the entire presence of the one anointing—so that the one anointing became man and the one anointed became God. — ORTHODOX FAITH 4:14
