Does not the ear test words as the tongue tastes food?
NIV
Is it not the task of the ear to discriminate between [wise and unwise] words, just as the mouth distinguishes [between desirable and undesirable] food?
AMP
Doth not the ear try words? and the mouth taste his meat?
KJV
You fasten my feet in shackles; you keep close watch on all my paths by putting marks on the soles of my feet.
NIV
You put my feet also in the stocks and observe critically all my paths; You set a circle and limit around the soles of my feet [which I must not overstep].
AMP
Thou puttest my feet also in the stocks, and lookest narrowly unto all my paths; thou settest a print upon the heels of my feet.
KJV
