'Prospered' in the Bible

So he said to Judah, “Let us build these cities and surround them with walls, towers, gates and bars [to secure the doors]. The land is still ours because we have sought the Lord our God; we have sought Him [longing for Him with all our heart] and He has given us peace on every side.” So they built and prospered.

Every work which he began in the service of the house of God in keeping with the law and the commandment, seeking and inquiring of his God [and longing for Him], he did with all his heart and prospered.

This same Hezekiah also stopped up the upper outlet of the waters of Gihon and channeled them down to the west side of the City of David. Hezekiah succeeded in everything that he did.
