Revelation of Jesus Christ

From the KJV 1611 with Strong's Concordance

Should we take an oath or swear an allegiance?

An excellent yet disturbing example of the pitfalls of oath taking can be found in the account of Herod Antipas when he had imprisoned John the Baptist. On his birthday whilst entertaining guests Herod asked Salome the daughter of his wife Herodias to dance for him and made an oath in front of his guests to give to her anything she wished even up to half of his kingdom. Salome went to her mother and asked her what should she should ask of Herod, her mother replied, ask for the head of John the Baptist. Herod was fond of John, and was not expecting that request but because he had taken the oath was caught in his own words resulting in him slaying a just man.
See Mark 6:14-29; Matthew 14:1-12; Luke 9:7-9.

In James 5:12 we read...

But above all things, my brethren, swear not, neither by heaven, neither by the earth, neither by any other oath: but let your yea be yea; and your nay, nay; lest ye fall into condemnation.

What is condemnation?

condemnation G2920 krisis {kree-sis} (subjectively or objectively, for or against); by extension a tribunal; by implication justice (specifically divine law); judgement, accusation, damnation.

Before taking an oath or swearing an allegiance be aware:
Oaths are binding ... a spoken contract ... do we really know who or what we are spiritually and physically binding ourselves to when taking an oath? ... We are warned ABOVE ALL THINGS to avoid all oaths unless we fall under divine judgement.

Let no one deceive you.
