'Fixed' in the Bible
My heart is steadfast, O God, my heart is steadfast and confident!I will sing, yes, I will sing praises [to You]!
You have defined and established all the borders of the earth [the divisions of land and sea and of the nations];You have made summer and winter.
He who dwells in the shelter of the Most HighWill remain secure and rest in the shadow of the Almighty [whose power no enemy can withstand].
O God, my heart is steadfast [with confident faith];I will sing, I will sing praises, even with my soul.
The works of His hands are truth and [absolute] justice;All His precepts are sure (established, reliable, trustworthy).
He will not fear bad news;His heart is steadfast, trusting [confidently relying on and believing] in the Lord.
He has also established them forever and ever;He has made a decree which shall not pass away.
