Jehovah demonstrated His power during the exodus from Egypt and during the wilderness wanderings. The proper response of Israel would have been fear and obedience. Instead, they chose to rebel and test Elohim. Because the people didn't believe in Elohim and trust in His salvation He was furious and kindled a fire against them.
Consider Jehovah's demonstrations of power in the past and realize that He is still powerful today. Don't rebel against Him. Don't test Him.
Psalm 78:12-25; ASV
12 Marvellous things did he in the sight of their fathers, in the land of Egypt, in the field of Zoan.
13 He clave the sea, and caused them to pass through; and he made the waters to stand as a heap.
14 In the day-time also he led them with a cloud, and all the night with a light of fire.
15 He clave rocks in the wilderness, and gave them drink abundantly as out of the depths.
16 He brought streams also out of the rock, and caused waters to run down like rivers.
17 Yet went they on still to sin against him, to rebel against the Most High in the desert.
18 And they tempted God in their heart by asking food according to their desire.
19 Yea, they spake against God; they said, can God prepare a table in the wilderness?
20 Behold, he smote the rock, so that waters gushed out, and streams overflowed; can he give bread also? Will he provide flesh for his people?
21 Therefore Jehovah heard, and was wroth; and a fire was kindled against Jacob, and anger also went up against Israel;
22 Because they believed not in God, and trusted not in his salvation.
23 Yet he commanded the skies above, and opened the doors of heaven;
24 And he rained down manna upon them to eat, and gave them food from heaven.
25 Man did eat the bread of the mighty: He sent them food to the full.
