and the head
<07218>

of Samaria
<08111>

[is] Remaliah's
<07425>

son
<01121>_.

If ye will not believe
<0539> (8686)_,

surely ye shall not be established
<0539> (8735)_.

{If...: or, Do ye not believe? it is because ye are not stable}

thee, saying

This [is] the way
<01870>_,

walk ye in it
<03212> (8798)_,

when ye turn to the right hand
<0541> (8686)_,

and when ye turn to the left
