The Bible describes filthy garments as a symbol of sin and uncleanliness, particularly in Isaiah 64:6, which states that our righteousness is like filthy rags.
In Isaiah 64:6, the scripture highlights the condition of humanity by stating that 'we are all as an unclean thing, and all our righteousnesses are as filthy rags.' This metaphor illustrates the deep-rooted sinfulness of man and the inadequacy of our own works to justify us before God. The high priest Joshua in Zechariah 3 is depicted standing in filthy garments, representing the sins he carries. Just as Joshua was shown to have his filthy garments removed and replaced with clean ones, this signifies the cleansing and imputation of Christ's righteousness, which completely transforms our standing before God. This transformation is essential for our acceptance before a holy God.
