Flesh and blood
The phrase “flesh and blood” carries layered meaning across the Bible, and its nuance shifts between the Old Testament (Hebrew Scriptures) and the New Testament (Greek Scriptures). Understanding this difference helps clarify themes about human nature, mortality, and spiritual transformation.
📜 Old Testament (Hebrew Bible) = Physical Life & Human Frailty
In the Old Testament, “flesh” (Hebrew: basar) and “blood” (dam) are usually literal and concrete, tied to life itself.
Key Themes:
- Life is in the blood
→ Leviticus 17:11 teaches that blood represents life given by God. - Human weakness and mortality
→ “All flesh” refers to humanity as fragile and temporary (see Isaiah 40:6). - Kinship / shared humanity
→ “Flesh and bone” expresses family ties (e.g., Genesis 2:23).
Example:
- Leviticus 17:11
“For the life of the flesh is in the blood…”
👉 Summary (Old Testament):
“Flesh and blood” emphasizes physical life, mortality, and dependence on God.
✝️ New Testament = Human Nature vs Spiritual Reality
In the New Testament, the phrase takes on a more symbolic and theological meaning, especially in the teachings of Jesus Christ and the writings of Paul the Apostle.
Key Themes:
- Human limitation vs divine revelation
→ Matthew 16:17
“Flesh and blood has not revealed this to you…”
(meaning: human understanding alone cannot grasp divine truth) - Mortal nature vs eternal kingdom
→ 1 Corinthians 15:50
“Flesh and blood cannot inherit the kingdom of God…” - Spiritual conflict beyond humans
→ Ephesians 6:12
“We wrestle not against flesh and blood…”
(the struggle is spiritual, not merely human)
Example:
- 1 Corinthians 15:50
“Flesh and blood cannot inherit the kingdom of God…”
👉 Summary (New Testament):
“Flesh and blood” represents human limitations, natural thinking, and mortality contrasted with spiritual life.
