2 Samuel 22:10

10 He made the sky sink
The verb נָטָה (natah) can carry the sense “[to cause to] bend; [to cause to] bow down” (see HALOT 693 s.v. נָטָה). For example, Gen 49:15 pictures Issachar as a donkey that “bends” its shoulder or back under a burden (cf. KJV, NASB, NRSV “He bowed the heavens”; NAB “He inclined the heavens”). Here the Lord causes the sky, pictured as a dome or vault, to bend or sink down as he descends in the storm.
as he descended;
a thick cloud was under his feet.
