'Cleave' in the Bible

And he who does not take his cross [expressing a willingness to endure whatever may come] and follow Me [believing in Me, conforming to My example in living and, if need be, suffering or perhaps dying because of faith in Me] is not worthy of Me.

Then Jesus said to His disciples, “If anyone wishes to follow Me [as My disciple], he must deny himself [set aside selfish interests], and take up his cross [expressing a willingness to endure whatever may come] and follow Me [believing in Me, conforming to My example in living and, if need be, suffering or perhaps dying because of faith in Me].

but whoever causes one of these little ones who believe in Me to stumble and sin [by leading him away from My teaching], it would be better for him to have a heavy millstone [as large as one turned by a donkey] hung around his neck and to be drowned in the depth of the sea.

And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh?

“He saved others [from death]; He cannot save Himself. He is the King of Israel; let Him now come down from the cross, and we will believe in Him and acknowledge Him.
