Genesis 31:39 That which was torn of beasts I brought not unto thee; I bare the loss of it; of my hand didst thou require it, whether stolen by day, or stolen by night. 40 Thus I was; in the day the drought consumed me, and the frost by night; and my sleep departed from mine eyes.
[Patriarchs & Prophets pp 190] For twenty years Jacob remained in Mesopotamia, laboring in the service of Laban, who, disregarding the ties of kinship, was bent upon securing to himself all the benefits of their connection. Fourteen years of toil he demanded for his two daughters; and during the remaining period, Jacob's wages were ten times changed. Yet Jacob's service was diligent and faithful. His words to Laban in their last interview vividly describe the untiring vigilance which he had given to the interests of his exacting master: “This twenty years have I been with thee; thy ewes and thy she-goats have not cast their young, and the rams of thy flock have I not eaten.
That which was torn of beasts I brought not unto thee; I bare the loss of it; of my hand didst thou require it, whether stolen by day, or stolen by night. Thus I was; in the day the drought consumed me, and the frost by night; and my sleep departed from mine eyes.” It was necessary for the shepherd to watch his flocks day and night. They were in danger from robbers, and also from wild beasts, which were numerous and bold, often committing great havoc in flocks that were not faithfully guarded. Jacob had many assistants in caring for the extensive flocks of Laban, but he himself was held responsible for them all.
During some portions of the year it was necessary for him to be constantly with the flocks in person, to guard them in the dry season against perishing from thirst, and during the coldest months from becoming chilled with the heavy night frosts. Jacob was the chief shepherd; the servants in his employ were the under-shepherds. If any of the sheep were missing, the chief shepherd suffered the loss; and he called the servants to whom he entrusted the care of the flock to a strict account if it was not found in a flourishing condition.
Proverbs 13:15 Good understanding giveth favor: but the way of transgressors is hard.
May God add His blessing to the study of His word. "Good night" and God bless!
