16:14
وَهُوَ ٱلَّذِى سَخَّرَ ٱلْبَحْرَ لِتَأْكُلُوا۟ مِنْهُ لَحْمًۭا طَرِيًّۭا وَتَسْتَخْرِجُوا۟ مِنْهُ حِلْيَةًۭ تَلْبَسُونَهَا وَتَرَى ٱلْفُلْكَ مَوَاخِرَ فِيهِ وَلِتَبْتَغُوا۟ مِن فَضْلِهِۦ وَلَعَلَّكُمْ تَشْكُرُونَ
And it is He who subjected the sea for you to eat from it tender meat and to extract from it ornaments which you wear. And you see the ships plowing through it, and [He subjected it] that you may seek of His bounty; and perhaps you will be grateful.

Tafsir
Ibn Kathīr (abridged)
Signs in the Oceans, Mountains, Rivers, Roads and Stars
Allah tells us how He has subjected the seas, with their waves lapping the shores, and how He blesses His servants by subjecting the seas for them so that they may travel on them, and by putting fish and whales in them, by making their flesh permissible to eat - whether they are caught alive or dead - at all times, including when people are in a state of Ihram. He has created pearls and precious jewels in the oceans, and made it easy for His servants to recover ornaments that they can wear from the ocean floor. He made the sea such that it carries the ships which plow through it. He is the One Who taught mankind to make ships, which is the inheritance of their forefather Nuh. He was the first one to travel by ship, he was taught how to make them, then people took this knowledge from him and passed it down from generation to generation through the centuries, so that they could travel from country to country and from place to place, bringing goods from here to there and from there to here. Thus Allah says:
وَلِتَبْتَغُواْ مِن فَضْلِهِ وَلَعَلَّكُمْ تَشْكُرُونَ
(that you may seek from His bounty and that you may perhaps be grateful.) - for His bounty and blessings. Then Allah mentions the earth and how He placed in it mountains standing firm, which make it stable and keep it from shaking in such a manner that the creatures dwelling on it would not be able to live. Hence Allah says,
وَالْجِبَالَ أَرْسَـهَا
(And the mountains He has fixed firmly.) (79: 32).
