'Prosper' in the Bible

Behold, God is with us at our head, and His priests [are here] with their signal trumpets to sound an alarm against you. O sons of Israel, do not fight against the Lord God of your fathers, for you cannot succeed.”

All the prophets prophesied this, saying, “Go up to Ramoth-gilead and succeed; the Lord will hand it over to the king.”

When he came to the king, the king said to him, “Micaiah, shall we go to Ramoth-gilead to battle, or shall I refrain?” And he said, “Go up and succeed, for they will be handed over to you.”

So they got up early in the morning and went out into the Wilderness of Tekoa; and as they went out, Jehoshaphat stood and said, “Hear me, O Judah, and you inhabitants of Jerusalem! Believe and trust in the Lord your God and you will be established (secure). Believe and trust in His prophets and succeed.”

Then the Spirit of God came over Zechariah the son of Jehoiada the priest, and he stood above the people and said to them, “This is what God has said: ‘Why do you transgress the commandments of the Lord so that you cannot prosper? Because you have abandoned (turned away from) the Lord, He has also abandoned (turned away from) you.’”

He continued to seek God in the days of Zechariah, who had understanding through the vision of God; and as long as he sought (inquired of, longing for) the Lord, God caused him to prosper.
