It is better that you should not vow than that you should vow and not pay.
Ecclesiastes 5:5

If you know these things, blessed are you if you do them.
John 13:17

The people of Joseph said to Joshua, “Why have you given us only one allotment and one portion for an inheritance? We are a numerous people, and the Lord has blessed us abundantly.” “If you are so numerous,” Joshua answered, “and if the hill country of Ephraim is too small for you, go up into the forest and clear land FOR YOURSELVES there in the land of the Perizzites and Rephaites.”
Joshua 17:14-15

The people of Joseph replied, “The hill country is not enough for us, and all the Canaanites who live in the plain have chariots fitted with iron, both those in Beth Shan and its settlements and those in the Valley of Jezreel.”
Joshua 17:16

But Joshua said to the tribes of Joseph—to Ephraim and Manasseh—“You are numerous and very powerful. You will have not only one allotment but the forested hill country as well. Clear it, and its farthest limits will be yours; though the Canaanites have chariots fitted with iron and though they are strong, you can drive them out.”
Joshua 17:17-18

But Caleb quieted the people before Moses and said, “Let us go up at once and occupy it, for we are well able to overcome it.”
Numbers 13:30

I was forty years old when Moses the servant of the Lord sent me from Kadesh Barnea to explore the land. And I brought him back a report according to my convictions, but my brothers who went up with me made the hearts of the people melt with fear. I, however, followed the Lord my God wholeheartedly.
Joshua 14:7-8

So on that day Moses SWORE to me, ‘The land on which your feet have walked WILL BE your inheritance and that of your children FOREVER, because you have followed the LORD my God wholeheartedly.’ Now give me this hill country that the LORD PROMISED ME that day. You yourself heard then that the Anakites were there and their cities were large and fortified, but, the LORD helping me, I will drive them out just as he said.”
Joshua 14:9,12

… live the rest of your earthly life no longer by human desires but by the will of God.
1 Peter 4:2

It is God who works in you to WILL and to ACT according to his good purpose.
Philippians 2:13

May the God of peace, who through the blood of the eternal covenant brought back from the dead our Lord Jesus, that great Shepherd of the sheep, equip you with everything good for doing his will, and may he work in us what is pleasing to him, through Jesus Christ, to whom be glory for ever and ever. Amen.
Hebrews 13:20
