Hosea 1:8

‘Now when she had weaned Lo-ruhamah, she conceived, and bore a son.'

The weaning of a child would take two or three years, giving Israel time to consider their ways, so that the next child to be born to Gomer would arrive some years later. But to those who did not consider repenting the waiting would be ominous. What warning would the next child bring? This time it was to be another son. God's message was slowly being brought home to Israel.
