'Fixed' in the Bible

It is for this that we labor and strive [often called to account], because we have fixed our [confident] hope on the living God, who is the Savior of all people, especially of those who believe [in Him, recognize Him as the Son of God, and accept Him as Savior and Lord].

Now a woman who is really a widow and has been left [entirely] alone [without adequate income] trusts in God and continues in supplications and prayers night and day.
