| Clarke's Commentary on the Bible His name was called Jacob - יעקב Yaccob, from עקב akab, to defraud, deceive, to supplant, i.e., to overthrow a person by tripping up his heels. Hence this name was given to Jacob, because it was found he had laid hold on his brother's heel, which was emblematical of his supplanting Esau, and defrauding him of his birthright.
Gill's Exposition of the Entire BibleAnd after that came his brother out,.... Out of his mother's womb, either by his own strength, or by the help of the midwife: and his hand took hold on Esau's heel; to pluck him back and get out first; and this was not casual, but was so ordered in Providence, and had a meaning and mystery in it: and his name was called Jacob; by his parents and others, and that for the above reason, because he took his brother by the heel, which his name has the signification of, and Esau has respect to in Genesis 27:36, and Isaac was threescore years old when she bare them; and so it was twenty years after he had been married to her; so long was his faith tried and exercised about the promised seed that was to spring from him.
Geneva Study BibleAnd after that came his brother out, and his hand took hold on Esau's heel; and his name was called Jacob: and Isaac was threescore years old when she bare them.
Wesley's Notes 25:26 His hand took hold on Esau's heel - This signified, Jacob's pursuit of the birth - right and blessing; from the first he reached forth to have catched hold of it, and if possible to have prevented his brother. His prevailing for it at last: that in process of time he should gain his point. This passage is referred to Hos 12:3, and from hence he had his name Jacob, a supplanter.
Matthew Henry's Concise Commentary25:19-26 Isaac seems not to have been much tried, but to have spent his days in quietness. Jacob and Esau were prayed for; their parents, after being long childless, obtained them by prayer. The fulfilment of God's promise is always sure, yet it is often slow. The faith of believers is tried, their patience exercised, and mercies long waited for are more welcome when they come. Isaac and Rebekah kept in view the promise of all nations being blessed in their posterity, therefore were not only desirous of children, but anxious concerning every thing which seemed to mark their future character. In all our doubts we should inquire of the Lord by prayer. In many of our conflicts with sin and temptation, we may adopt Rebekah's words, If it be so, why am I thus? If a child of God, why so careless or carnal? If not a child of God, why so afraid of, or so burdened with sin? |
