Psalms 68:8

the earth shakes, yes, the heavens pour down rain before God, the God of Sinai, ¹  before God, the God of Israel. ² 

Ex 19:16,18; De 5:23-25; Jud 5:4,5; Ps 41:13; Ps 68:35; Ps 77:18; Ps 114:7; Isa 45:3; Isa 64:1,3; Hab 3:13; Heb 12:26; Re 11:19

¹ tn Heb “this one of Sinai.” The phrase is a divine title, perhaps indicating that the Lord rules from Sinai.

² sn The language of vv. 7-8 is reminiscent of Judg 5:4-5, which tells how the God of Sinai came in the storm and annihilated the Canaanite forces led by Sisera. The presence of allusion does not mean, however, that this is a purely historical reference. The psalmist is describing God’s typical appearance as a warrior in terms of his prior self-revelation as ancient events are reactualized in the psalmist’s experience. (For a similar literary technique, see Hab 3.)
