Exodus 17:3

Exodus 17:3
And the people thirsted there for water; and the people murmured against Moses, and said, Wherefore is this that thou hast brought us up out of Egypt, to kill us and our children and our cattle with thirst?

Freed from bondage, you nourished your people - feeding them and giving them water to drink. But it was not enough, because their spirits were still hard. So you gave Jesus, bread and water of life, fulfillment of prophecy and gift beyond measure. You always know what we need and always deliver, so I need not worry.
