Matthew Henry on Genesis 35:6-15
Jacob and his retinue having safely arrived at Bethel, we are here told what passed there.
I. There he built an altar (Gen 35:7), and no doubt offered sacrifice upon it, perhaps the tenth of his cattle, according to his vow, I will give the tenth unto thee. With these sacrifices he joined praises for former mercies, particularly that which the sight of the place brought afresh to his remembrance; and he added prayers for the continuance of God's favour to him and his family.
