'Accept' in the Bible

and if you are willing to accept [it], he is Elijah, the one who is going to come.

But he said to them, "Not everyone can accept this saying but [those] to whom it has been given.

For there are eunuchs who were born as such from [their] mother's womb, and there are eunuchs who were made eunuchs by people, and there are eunuchs who have made themselves [eunuchs] for the sake of the kingdom of heaven. The one who is able to accept [this], let him accept [it]."
