'Certain' in the Bible

All this he let you see, so that you might be certain that the Lord is God and there is no other.

So today be certain, and keep the knowledge deep in your hearts, that the Lord is God, in heaven on high and here on earth; there is no other God.

Be certain, then, that the Lord your God is God; whose faith and mercy are unchanging, who keeps his word through a thousand generations to those who have love for him and keep his laws;

And it is certain that if at any time you are turned away from the Lord your God, and go after other gods, to be their servants and to give them worship, destruction will overtake you.

Be certain then today that it is the Lord your God who goes over before you like an all-burning fire; he will send destruction on them, crushing them before you; and you will send them in flight, putting an end to them quickly, as the Lord has said.

Be certain then that the Lord your God is not giving you this good land as a reward for your righteousness; for you are a stiff-necked people.

And be certain in your minds this day; for these words are not said to your children, who have had no experience of the training of the Lord your God, and who have not seen his great power or his strong hand and his stretched-out arm,

Then let a full search be made, and let questions be put with care; and if it is true and certain that such a disgusting thing has been done among you;

And if you say in your hearts, How are we to be certain that the word does not come from the Lord?

Only those trees which you are certain are not used for food may be cut down and put to destruction: and you are to make walls of attack against the town till it is taken.

If their owner is not near, or if you are not certain who he is, then take the beast to your house and keep it till its owner comes in search of it, and then you are to give it back to him.

But be certain to give it back to him when the sun goes down, so that he may have his clothing for sleeping in, and will give you his blessing: and this will be put to your account as righteousness before the Lord your God.

Your very life will be hanging in doubt before you, and day and night will be dark with fears, and nothing in life will be certain:

For I am certain that after my death you will give yourselves up to sin, wandering from the way which I have given you; and evil will overtake you in the end, because you will do evil in the eyes of the Lord, moving him to wrath by the work of your hands.
