'Sperm' in the Bible

Every garment and every leather on which there is semen shall be washed with water, and shall be unclean until evening.

This is the law for the one who has a discharge and for the one who has a seminal emission, so that he is unclean by it;

for you have been born again [that is, reborn from above—spiritually transformed, renewed, and set apart for His purpose] not of seed which is perishable but [from that which is] imperishable and immortal, that is, through the living and everlasting word of God.

No one who is born of God [deliberately, knowingly, and habitually] practices sin, because God’s seed [His principle of life, the essence of His righteous character] remains [permanently] in him [who is born again—who is reborn from above—spiritually transformed, renewed, and set apart for His purpose]; and he [who is born again] cannot habitually [live a life characterized by] sin, because he is born of God and longs to please Him.
