'Be Holy' in the Bible

“You shall be holy men to Me; therefore you shall not eat meat [from any animal] that has been torn to pieces [by predators] in the field; you shall throw it to the dogs.

For seven days you shall make atonement for the altar [of burnt offering] and consecrate it; then the altar shall be most holy. Whatever touches the altar must be holy (set apart for God’s service).

You shall consecrate them, that they may be most holy; whatever touches them must be holy (set apart for God).

Then you shall take the anointing oil and anoint the tabernacle and all that is in it, and consecrate it and all its furniture; and it shall be holy (declared sacred, separated from secular use).
