Bind them continually upon thine {i} heart, and tie them about thy neck.

(i) Pr 3:3.

Wesley's Notes

6:21 Bind them - Constantly remember, and duly consider them.

Matthew Henry's Concise Commentary

6:20-35 The word of God has something to say to us upon all occasions. Let not faithful reproofs ever make us uneasy. When we consider how much this sin abounds, how heinous adultery is in its own nature, of what evil consequence it is, and how certainly it destroys the spiritual life in the soul, we shall not wonder that the cautions against it are so often repeated. Let us notice the subjects of this chapter. Let us remember Him who willingly became our Surety, when we were strangers and enemies. And shall Christians, who have such prospects, motives, and examples, be slothful and careless? Shall we neglect what is pleasing to God, and what he will graciously reward? May we closely watch every sense by which poison can enter our minds or affections.
