When Abraham and his allies came back from crushing the four kings, the king of Sodom and the King of Salem came to meet them. In the mind of the Sodom king was material and people and possessions, and he wanted to look generous and offered Abraham all the spoil he brought back. But Abraham knew the kings in the Jordan valley, their sinful ways and said no, he didn’t want them to brag about making him rich.
But the other king, Melchizedek king of Salem that came had God in his heart and mind and understood that the people coming from battle needed food and drink. Did he praise Abraham and his allies for what they achieved, no, Melchizedek praised and glorified the God most high, he used the Hebrew word El Elyon, meaning “The supreme Ruler of the entire universe; His dominion is all encompassing and everlasting. “
Melchizedek knew that God had Given Abraham the victory and blessed Abraham and Abraham knew that the high priest the king of Salem also needed material support and gave him tenth of all that they had gained in the battle. We need our Christian leaders and their care, but they also need our giving.
