c. 10th - 9th century BC
After the death of King Solomon, the kingdom of Israel split into the Northern and Southern Kingdoms. Solomon's son Rehoboam reigned over Judah (the Southern Kingdom) for 17 years. After this, Rehoboam's son Abijah reigned in Judah 3 years. During these years, there was war between the Northern and Southern kingdoms. On one occasion, King Abijah of Judah went out to battle with Israel (the northern kingdom) with an army only half the size of Israel's army. Yet, King Abijah declared to his opponents: "O children of Israel, do not fight against the LORD God of your fathers, for you shall not prosper!"
they (trusted in / relied upon / relied on) the LORD
After King Abijah died, his son Asa reigned in his place. During the reign of King Asa, an army from Ethiopia came up against them. When Judah's army went out to meet them at Mareshah and prepared for battle, King Asa said:
"we (trust in / rely on / rest on) You"
After King Asa died, his son Jehoshaphat reigned in his place. During the reign of King Jehoshaphat, an army from Moab, Ammon, and other places came up against him. The king was afraid when he heard about this great multitude, so he "set himself to seek the LORD." The people assembled in the temple in Jerusalem and there, King Jehoshaphat prayed to God. God answered him through a prophet named Jahaziel and told them not to fear, but to go down against them the next day, position themselves and "stand still and see the salvation of the LORD, who is with you, O Judah and Jerusalem!" They did this, and "as they went out, Jehoshaphat stood and said":
"(put your trust in / have faith in / believe in) the LORD your God"
