It is Corban
Matthew 15:5
But ye say, Whosoever shall say to his father or his mother, It is a gift, by whatsoever thou mightest be profited by me;
Matthew 23:18
And, Whosoever shall swear by the altar, it is nothing; but whosoever sweareth by the gift that is upon it, he is guilty.
1 Timothy 5:4-8
4
But if any widow have children or nephews, let them learn first to shew piety at home, and to requite their parents: for that is good and acceptable before God.
5
Now she that is a widow indeed, and desolate, trusteth in God, and continueth in supplications and prayers night and day.
6
But she that liveth in pleasure is dead while she liveth.
7
And these things give in charge, that they may be blameless.
8
But if any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel.
