'En dorsement' in the Bible

And evil spirits also came out of many people, shouting [at Him], "You are the Son of God." And Jesus spoke sternly to them and would not allow them to speak [anymore] because they knew He was the Christ [Note: Jesus would not accept the endorsement of these Satanic spirits].

Do not work for food that perishes, but for food that endures [and leads] to eternal life, which the Son of Man will give you; for God the Father has authorized Him and put His seal on Him.”

If anyone comes to you [i.e., to your meetings] who does not bring this teaching [about Christ], you should not welcome him into your home or give him [any] greetings [i.e., suggesting approval or endorsement].
