'Strength' in the Bible

I am not able by myself to take the weight of all this people, for it is more than my strength.

Only, do not go against the Lord or go in fear of the people of the land, for they will be our food; their strength has been taken from them and the Lord is with us: have no fear of them.

But he said, You are not to go through. And Edom came out against them in his strength, with a great army.

Peoples will be in fear before his strength, his arm will be on great nations: his king will be higher than Agag, and his kingdom made great in honour.

And Israel will go on in strength, and Jacob will have rule over his haters.
