Malaquias 2

15 And did not Hashem make echad?

And the remnant of the ruach is Hashemʼs.

And why echad?

That He might seek zera Elohim.

Therefore be shomer of your ruach,

and let none deal treacherously against the wife of his youth.

16 For Hashem Elohei Yisroel saith

that He hateth putting away:

for it covereth oneʼs garment with chamas (violence),

saith the Hashem Tzva’os:

therefore, be shomer of your ruach,

that ye deal not treacherously, breaking faith.
