'Shoulder' in the Bible

For if anyone thinks he is something [special] when [in fact] he is nothing [special except in his own eyes], he deceives himself.

For even though I am absent [from you] in body, nevertheless I am with you in spirit, delighted to see your good discipline [as you stand shoulder to shoulder and form a solid front] and to see the stability of your faith in Christ [your steadfast reliance on Him and your unwavering confidence in His power, wisdom, and goodness].
