Problem: Verse 13 – Now all has been heard; here is the conclusion of the matter: Fear God and keep His commandments, for this is the whole duty of man.” Some might say, “Well, this is the Old Testament. We don’t have live under that anymore.”
Solution: Verse 14 – For God will bring every deed into judgment, including every hidden thing, whether it is good or evil. The solution begins with verse 14 as it tells us that every deed of man will be judged. With those who say this we are not under the Old Testament anymore, we need to see if we have any verses in the New Testament that tells us that all our deeds will be judged. We also need to see if we have anything in the New Testament that tells us we are to be keeping the commands of God as established in the Old Testament. The sentiments of Ecclesiastes 12:14 are echoed here: Revelation 22:12 – “Behold, I am coming soon! My reward is with me, and I will give to everyone according to what he has done.” They are also related in Revelation 20:12-13, Jude 1:14-15, 2 Corinthians 5:10, and Romans 2:6.
Problem: verse 13 – “If you turn back your foot from the Sabbath, from doing your pleasure
on my holy day, and call the Sabbath a delight and the holy day of the LORD honorable; if you honor it, not going your own ways,” Some understand “doing your pleasure” to mean we cannot do anything we enjoy on Shabbat.
Solution: Genesis 15:13 and Leviticus 23:26-32, along with several other verses, defines what it means to refrain from doing one’s own pleasure, or humbling one’s self on the Sabbath. This is not working, so we are not to work nor have other’s work for us on the Sabbath. Just before in the same chapter (verses 3-4) we have Yahweh defining what He wants done, and how we are to fast versus what the Pharisees were doing. Doing their own pleasure had to do with working or having others work for them. So, here in verse 13 we are told if we keep ourselves from working on the Sabbath, not keep ourselves from doing something we enjoy whether it be relaxing, crocheting, or something else. We are to love the Word of God and it should be a joy and pleasure to read, study, and learn. If doing such is a pleasure for us, should we refrain from it on Shabbat as well? Of course not.
