The warning here is a reminder that the Israelites’ unbelief kept almost all of them from entering into the land that God had promised them. Their unbelief was well illustrated in Exodus Exodus 17:1-7, when they complained against Moses and doubted that God was with them.
This quotation comes from the Old Testament in the book of Psalms.
God’s “voice” represents him speaking. AT: “when you hear God speak” (See: rc://en/ta/man/translate/figs-metonymy)
“Hearts” here is a metonym for “thoughts and intentions.” AT: “do not be stubborn” (See: rc://en/ta/man/translate/figs-metonymy)
Here “rebellion” and “testing” can be stated as verbs. AT: “as when your ancestors rebelled against God and tested him in the wilderness” (See: rc://en/ta/man/translate/figs-abstractnouns)
