Biblical basis for treating a second marriage as sinful even in cases of adultery?

| Matthew 19:9 (NIV) | | -- | | I tell you that anyone who divorces his wife, except for sexual immorality, and marries another woman commits adultery. | Many Christians believe it is okay to remarry if a previous marriage ended due to adultery. However, there are Pentecostal strands in my country that regard any second marriage as sinful and adulterous regardless of whether the prior marriage was dissolved due to spousal infidelity. Is there a biblical basis for this view, especially one focused on Matthew 19:9? one of the strongest arguments is that the word sexual immorality refers to fornication with the current woman, that is, there is no marriage, so it would not be a sin to marry another woman because the individual would be in fornication with the current woman, but this translation uses "divorce" not "separate", presuming a previous marriage with his atual woman.
