'Cause' in the Bible

The king told them, “Take the servants of your lord with you and have Solomon my son ride on my own mule, and bring him down to [the spring at] Gihon [in the Kidron Valley].

then hear in heaven their prayer and their pleading, and maintain their right and defend their cause.

then hear their prayer and their supplication in heaven Your dwelling place, and maintain their right and defend their cause,

Let these words of mine, with which I have made supplication before the Lord, be near to the Lord our God day and night, so that He will maintain the cause and right of His servant and of His people Israel as each day requires,
