Deuteronomy 33:9-11

He has said to his father and to his mother, 'I do not know you,' and to his brothers, 'I will disregard you.' And they have not known their own sons. Such as these have kept your word and have observed your covenant: your judgments, O Jacob, and your law, O Israel. They shall place incense before your fury and a holocaust upon your altar. O Lord, bless his strength, and receive the works of his hands. Strike the backs of his enemies, and do not let those who hate him rise up."
