Divorce And Bible

divorce and bible
Where in the bible does it condemn divorce?

I’m writing a paper and need to know where in the bible does it say that a sacramental marriage cannot be broken.

Mal 2:16 For the LORD, the God of Israel, saith that he hateth putting away: for [one] covereth violence with his garment, saith the LORD of hosts: therefore take heed to your spirit, that ye deal not treacherously.

“putting away” is divorce

1Cr 7:39 The wife is bound by the law as long as her husband liveth; but if her husband be dead, she is at liberty to be married to whom she will; only in the Lord.

1Cr 7:10 ¶ And unto the married I command, [yet] not I, but the Lord, Let not the wife depart from [her] husband:

1Cr 7:11 But and if she depart, let her remain unmarried, or be reconciled to [her] husband: and let not the husband put away [his] wife.
