2 Samuel 23:5

23:5 My dynasty is approved by God,

for he has made a perpetual covenant with me,

arranged in all its particulars and secured.

He always delivers me,

and brings all I desire to fruition.

Psalms 89:28-34

89:28 I will always extend my loyal love to him,

and my covenant with him is secure.

89:29 I will give him an eternal dynasty,

and make his throne as enduring as the skies above.

89:30 If his sons reject my law

and disobey my regulations,

89:31 if they break my rules

and do not keep my commandments,

89:32 I will punish their rebellion by beating them with a club,

their sin by inflicting them with bruises.

89:33 But I will not remove my loyal love from him,

nor be unfaithful to my promise.

89:34 I will not break my covenant

or go back on what I promised.

Psalms 89:39

89:39 You have repudiated your covenant with your servant;

you have thrown his crown to the ground.

Jeremiah 33:20-26

33:20 “I, Lord, make the following promise: ‘I have made a covenant with the day and with the night that they will always come at their proper times. Only if you people could break that covenant 33:21 could my covenant with my servant David and my covenant with the Levites ever be broken. So David will by all means always have a descendant to occupy his throne as king and the Levites will by all means always have priests who will minister before me. 33:22 I will make the children who follow one another in the line of my servant David very numerous. I will also make the Levites who minister before me very numerous. I will make them all as numerous as the stars in the sky and as the sands which are on the seashore.’”

33:23 The Lord spoke still further to Jeremiah. 33:24 “You have surely noticed what these people are saying, haven’t you? They are saying, ‘The Lord has rejected the two families of Israel and Judah that he chose.’ So they have little regard that my people will ever again be a nation. 33:25 But I, the Lord, make the following promise: I have made a covenant governing the coming of day and night. I have established the fixed laws governing heaven and earth. 33:26 Just as surely as I have done this, so surely will I never reject the descendants of Jacob. Nor will I ever refuse to choose one of my servant David’s descendants to rule over the descendants of Abraham, Isaac, and Jacob. Indeed, I will restore them and show mercy to them.”
