Psalms 18:9

18:9 He made the sky sink ¹  as he descended;

a thick cloud was under his feet.

Psalms 97:2

97:2 Dark clouds surround him;

equity and justice are the foundation of his throne. ² 

[18:9]  ¹ tn The Hebrew verb נָטָה (natah) can carry the sense “[cause to] bend, bow down.” For example, Gen 49:15 pictures Issachar as a donkey that “bends” its shoulder or back under a burden. Here the Lord causes the sky, pictured as a dome or vault, to sink down as he descends in the storm.

[97:2]  ² sn The Lord’s throne symbolizes his kingship.
