'Strong' in the Bible

From Aroer, which is on the edge of the Arnon Valley, and from the city which is in the valley, as far as Gilead, there was no city [whose wall was] too high and too strong for us; the Lord our God handed over everything to us.

“Therefore, you shall keep all the commandments which I am commanding you today, so that you may be strong and go in and take possession of the land which you are crossing over [the Jordan] to possess;

You may spend the money for anything your heart desires: for oxen, or sheep, or wine, or [other] strong drink, or anything else you want. You shall eat there in the presence of the Lord your God and rejoice, you and your household.

You have not eaten bread, nor have you drunk wine or strong drink, so that you might know that I am the Lord your God [on whom you must depend].

Be strong and courageous, do not be afraid or tremble in dread before them, for it is the Lord your God who goes with you. He will not fail you or abandon you.”

Then Moses called to Joshua and said to him in the sight of all [the people of] Israel, “Be strong and courageous, for you will go with this people into the land which the Lord has sworn to their fathers to give them, and you will give it to them as an inheritance.

Then it shall come about, when many evils and troubles have come on them, that this [sacred] song will confront them as a witness; for it will not be forgotten from the mouth of their descendants. For I know their inclination which is developing even now, before I bring them into the land which I have sworn to give them.”

Then He commanded and commissioned Joshua, the son of Nun, and said, “Be strong and courageous, for you will bring the sons of Israel into the land which I have sworn to give them, and I will be with you.”
