God hates infidelity (sexual and financial) between couples. A healthy marriage will have caring, responsible, open and transparent husband and honest, God-fearing wife.
“Help, Lord; for the godly man ceaseth; for the faithful fail from among the children of men.’ = Psalm 12: 1
“And if ye have not been faithful in that which is another man’s, who shall give you that which is your own?” – Luke 16: 12
“Moreover it is required in stewards, that a man be found faithful.” – 1Corinthians 4: 2
