'Flesh' in the Bible

Since then the children have shared in flesh and blood, he also himself in the same way partook of the same, that through death he might bring to nothing him who had the power of death, that is, the devil,

He, in the days of his flesh, having offered up prayers and petitions with strong crying and tears to him who was able to save him from death, and having been heard for his godly fear,

For if the blood of goats and bulls, and the ashes of a heifer sprinkling those who have been defiled, sanctify to the cleanness of the flesh:

by the way which he dedicated for us, a new and living way, through the veil, that is to say, his flesh;

Furthermore, we had the fathers of our flesh to chasten us, and we paid them respect. Shall we not much rather be in subjection to the Father of spirits, and live?
