Ezekiel 27:7 says, Fine linen with broidered work from Egypt was that which thou spreadest forth to be thy sail; blue and purple from the isles of Elishah was that which covered thee. God said that the sails of the ships of Tyrus had been made of fine linen and were brightly colored. This showed how prosperous they were, but it was all temporary wealth. We may adorn ourselves in the finest clothes, live in mansions, and drive fancy cars, but these things are all temporary and one day will be done away with, if not in this lifetime, then when we face God in judgment. This is especially true for those who have gained these things while denying God, but it also applies to the things of this world that Christians have amassed.
Verse eight adds, The inhabitants of Zidon and Arvad were thy mariners: thy wise men, O Tyrus, that were in thee, were thy pilots. God said that the people of Tyrus had the inhabitants of Zidon as their mariners and that the wise men of Tyrus had been their pilots. Zidon was a sister city to Tyrus, and the people there were important to the success of Tyrus. God also said it was good that the people of Tyrus could provide their own pilots. We may have someone lead us to knowledge of God and even lead us to do the right thing, but until we accept His gift of salvation for ourselves, we will not be saved.
Verse nine continues, The ancients of Gebal and the wise men thereof were in thee thy calkers: all the ships of the sea with their mariners were in thee to occupy thy merchandise. God then points out other people who helped in the ship building, all doing what they were best at. We need each other as Christians today, and we need to do what we are best at, which should also be what God has called us to do.
Verse ten states, They of Persia and of Lud and of Phut were in thine army, thy men of war: they hanged the shield and helmet in thee; they set forth thy comeliness. God said the people of Tyrus looked to other nations to protect them militarily, and even if we as a nation believe that we can stand alone to protect ourselves, if we are not basing this on our obedience to God, it will never be true.
Verse eleven continues, The men of Arvad with thine army were upon thy walls round about, and the Gammadims were in thy towers: they hanged their shields upon thy walls round about; they have made thy beauty perfect. God continued to remind them of those other people that they depended on for their protection. Ultimately, we depend on God for our protection, but He may help us find this protection through our alliances with other nations or other people, but especially other Christians.
