'Wherefore' in the Bible

Wherefore it shall come to pass, if ye hearken to these judgments, and keep, and do them, that the LORD thy God shall keep unto thee the covenant and the mercy which he sware unto thy fathers:

Wherefore Levi hath no part nor inheritance with his brethren; the LORD is his inheritance, according as the LORD thy God promised him.

Wherefore I command thee, saying, Thou shalt separate three cities for thee.

Even all nations shall say, Wherefore hath the LORD done thus unto this land? what meaneth the heat of this great anger?
