Another interpretation: "The Lord will answer you on a day of trouble." A father and son were traveling when the son became tired and asked his father, "Where is the country?" The father replied, "My son, if you see a cemetery in front of you, know that the country is close to you." So the Lord said to Israel, "If you see that troubles are covering you at that time, you will be redeemed," as it is said, "The Lord will answer you on a day of trouble; He will shelter you with the shelter of Jacob.
The God of Abraham and the God of Isaac are not mentioned here, only the God of Jacob. Why did Resh Lakish say, "It is like a pregnant woman who has difficulty giving birth. They said to her, "We do not know what to say to you, but whoever answered your mother in her difficult time will answer you in your difficult time." So it is written about Jacob, "To the Almighty who answered me on the day of my distress."
David said, "Just as the Lord answered Jacob your father in his time of trouble, He will answer you in your time of trouble." "May the Lord answer you on a day of trouble; may the name of the God of Jacob protect you."
