Psalm 106:13, "They soon forgot his works. They didn’t wait for his counsel," describes the Israelites' behavior after God had delivered them from Egypt and demonstrated his power through miracles. Let's break down the meaning:

"They soon forgot his works": This refers to the miracles and acts of deliverance that God had performed for them. They quickly disregarded the evidence of God's power and faithfulness. This is a key aspect of their sin – they didn't retain the lessons and gratitude they should have derived from God's actions on their behalf. Remember, the exodus was a monumental demonstration of God's power: the plagues, the parting of the Red Sea, the defeat of the Egyptian army. To forget these so quickly reveals a shallow faith.

"They didn’t wait for his counsel": Instead of seeking God's guidance and direction, they acted impulsively, based on their own desires and impatience. "Counsel" here refers to God's wisdom, instruction, and guidance, which was accessible to them through Moses and other means. By not waiting, they demonstrated a lack of trust in God's plan and a preference for their own short-sighted solutions. They wanted what they wanted, and they wanted it now, even if it meant disobeying God.

In essence, the verse highlights the Israelites':

Ingratitude: They didn't appreciate or remember God's past blessings.
Impatience: They were unwilling to wait for God's timing and guidance.
Lack of Trust: They didn't rely on God's wisdom and power to lead them.
Self-Reliance: They depended on their own judgment instead of God's.

The verse serves as a warning against repeating the Israelites' mistakes and encourages believers to remember God's faithfulness, seek his counsel, and trust in his guidance. It's a call to cultivate a deeper, more patient, and trusting relationship with God. It is a demonstration of the human tendency to forget God's blessings and favor.
