Okla. Stat. tit. 21, § 21-390

Every officer to whose charge any juror or jury is committed by

any court or magistrate, who negligently or willfully permits them,

or any one of them, either:

1. To receive any communication from any person;

2. To make any communication to any person;

3. To obtain or receive any book or paper or refreshment; or

4. To leave the jury room, the jury box, or his immediate

custody or control, without the leave of such court or magistrate

first obtained, is guilty of a misdemeanor.

Every bailiff, or other officer or person, into whose custody

and care any court of record contemplates committing any juror or

jury, before entering upon his duties as such for the court term or

such lesser period of such service as the court may determine, shall

first be admonished and shall make in writing and file with the

clerk of such court a solemn oath, sworn to before the clerk or

judge of such court, to the effect that he will regard the foregoing

provisions of this section and that he will faithfully prevent the

same and obstruct any attempt to accomplish or to attempt to do any

of them, but at the same time to have regard to the comfort and

well-being of the jurors and all of them, entrusted into his care in

each and every jury trial in any cause during such court term or

lesser period of appointment by such court.

In every court the same admonition shall be given and the same

oath required as above, in each jury trial; but the court shall have

the option whether the same be oral, or in writing and filed in such

case, but thereafter during the trial of the same cause and until

such jury is dismissed from further consideration of the same it

shall not be necessary, for all intent and purposes of this act, to

administer again such admonition or to require such oath.
