'Single' in the Bible

whereas Christ, having offered the one sacrifice [the all-sufficient sacrifice of Himself] for sins for all time, sat down [signifying the completion of atonement for sin] at the right hand of God [the position of honor],

For by the one offering He has perfected forever and completely cleansed those who are being sanctified [bringing each believer to spiritual completion and maturity].

and [see to it] that no one is immoral or godless like Esau, who sold his own birthright for a single meal.
