Proverbs 5:2

That thou mayest regard
<08104> (8800)

discretion
<04209>_,

and [that] thy lips
<08193>

may keep
<05341> (8799)

knowledge
<01847>_.

Proverbs 23:16

Yea, my reins
<03629>

shall rejoice
<05937> (8799)_,

when thy lips
<08193>

speak
<01696> (8763)

right things
<04339>_.

Let another man
<02114> (8801)

praise
<01984> (8762)

thee, and not thine own mouth
<06310>_;

a stranger
<05237>_,

and not thine own lips
<08193>_.

For [it is] a pleasant thing
<05273>

if thou keep
<08104> (8799)

them within
<0990>

thee; they shall withal
<03162>

be fitted
<03559> (8735)

in thy lips
<08193>_.

{within...: Heb. in thy belly}
