Psalms 81:7

7 In your distress you called out and I rescued you.
I answered you from a dark thundercloud.
Heb “I answered you in the hidden place of thunder.” This may allude to God’s self-revelation at Mount Sinai, where he appeared in a dark cloud accompanied by thunder (see Exod 19:16).

I tested you at the waters of Meribah.
The name Meribah means “strife.” Two separate but similar incidents at the place called Meribah are recorded in the Pentateuch (Exod 17:1–7; Num 20:1–13). In both cases the Israelites complained about lack of water and the Lord miraculously provided for them.
(Selah)
