When Isaac blesses Jacob (believing him to be Esau), he declares 'I have made him your lord' and later laments 'I have made him your lord.' This term denotes mastery and authority within family or clan structures, establishing hierarchy and dominance. The root relates to might and strength, suggesting that lordship involved not just social position but the power to enforce one's will. In these Genesis passages, the word captures the irrevocable nature of patriarchal blessing—once lordship is pronounced, it cannot be withdrawn.
