C. F. Keil and Franz Delitzsch on Genesis 47:15-17

Gen 47:15-17

When the money was exhausted, the Egyptians all came to Joseph with the petition: “Give us bread, why should we die before thee” (i.e., so that thou shouldst see us die, when in reality thou canst support us)? Joseph then offered to accept their cattle in payment; and they brought him near their herds, in return for which he provided them that year with bread. נהל: Piel to lead, with the secondary meaning, to care for (Psa 23:2; Isa 40:11, etc.); hence the signification here, “to maintain.”
