for they will add length to your days, years and peace to your life.
Wisdom promises not mere length of days but years of life eternal; Christ holds length of days forever in His right hand and gives it to all His children. The Gospel itself is peace, and its doctrines, justification by His righteousness, pardon by His blood, atonement by His sacrifice, are the very means of giving and increasing spiritual peace in believers' hearts.
AI summary
For length of days, and long life, and peace, shall they add to thee. (a) Long life is the blessing of God which he gives to his, so far as it is expedient for them.
God's law must be fixed in your heart, not merely lodged in your head; your will and affections must bend to it as the ark bends to the mercy seat. Obey His commandments and you shall have not only length of days but peace added to you continually, even into eternity.
